I think Nintendo took the advantage that most of their games were more oriented for kid-like games that didN't require good graphics as much and spent most of their time trying to find an innovative way to entertain people, and the hardware suffered.
That is quite likely, however the other possibility is that it is far cheaper to use older, slower components, thus increasing net profit.

Once new systems comes out the Wii will fall behind pretty quick in sales, though, and now they compete vs the Kinect and PS Move.
I'm sure they are working on a motion sensing peripheral right now.

And yeah fonts are adjustable on the Nspire. I just mean that if TI decides to use a higher res screen, they'll need to make sure to do like Casio and adjust text size in consequence.
If they ever choose to use a high quality, high resolution screen I'm sure they would make the fonts readable. Such an event is exceedingly unlikely, given TI's cheap habits, because high quality screens are very expensive.

I think the main issue is offer/demand. Nintendo has an history of selling their consoles cheaper on launch. I remember the N64 for example. However, since they become very popular their price won't drop as fast. I remember the 360 was like $300 cheaper 3 years after launch, and today the Wii only dropped by about $60 over here (compared to the launch price).
Yes, the price of the 360 has changed a lot relative to the prices of other consoles.

Quote
Maybe Nintendo has cheaper hardware for the price ratio, but it doesn't mean their consoles are bad. They're just for a different group of people.
Which is pretty much what I said in my previous post. Only problem is that's not a very good excuse to use relatively crappy components to make more money.

Quote
However, something seems wrong with your image above: Where I live the 360 costed about $700 on launch, not $300. Was it really this cheap in USA when it came out? O.O
Only if you could find one.

I think TI is much more worse than Nintendo on the hardware/ratio point, and on the TI-Nspire, less freedom.
Yes, TI has worse price/value ratios than Nintendo, but the Wii and DS are far more locked down then the Nspire. There is no Wii-BASIC or anything like it.

Quote
Also personally as much as I wish the CX screen was a lot larger, I would rather have it so it's small enough to allow the calc to fit in a pocket. I feel the TI-Nspire is too huge, compared to the Prizm.
This is simply a matter of personal preference, there isn't anything to discuss here.

Quote
Also, if the resolution was larger I would surely hope the text is still readable. If they decided to use a 720x480 LCD, but the entire text was 8 px fonts, it would hurt our eyes. I already find the text small enough on the Nspire Clickpad and the TI-89T.
Fortunately, this would not be an issue. The iPhone 4's display has a very high pixel density, and yet it is one of the clearest and easiest to read displays in use. The problem you're referring to is merely a font size issue. I believe that is somewhat adjustable on the Nspire.

Quote
Anyway I guess everyone got their opinions, but in your earlier comment, mikehill2003, it sounded like you were totally against a color screen and the way the rest was worded it seemed like you were against calc dev and thought they were reserved only for math.
No, I think a color screen is a great thing, but TI uses it as a shield against the Nspire's other problems (such as the weak CPU). As in "Look, our new TI-Nspire CX has a shiny color screen!" "I see. Does it use a modern 800Mhz CPU yet?" "Look, the ability to draw graphs onto images will revolutionize teaching!"

I'm not against calc game dev at all. I personally don't have enough free time right now to do it, but I fully appreciate the effort that goes into calc games. Features that make a calculator great for game development, like a great screen, plenty of memory, and good programming support also make it great for serious things like mathematics.

Quote
We need to be careful about how we word stuff and also some people are more sensitive so if they arrive with a CX or a Prizm and you go tell them this calc is worthless because of the hardware they might think you are telling them they're worthless.
I agree, but don't consider any decent calculator worthless, much less its owner.

Quote
And one thing to remember is that Omnimaga doesn't welcome fanboyism towards consoles, OSes, browsers, languages, etc, so we have to be careful to make sure what we say doesn't sound like it comes from a fanboy.
Don't worry, I'm not really a fanboy of any kind. I care far more about an individual product's worth on its own then the company or philosophy that led to its development. In other words, I'd gladly sell my iPod if someone made a faster and cheaper Android alternate.

I don't think that's a sensible comparison to make.

As a way to say "Never buy a console, and if you do, make sure it's not a Wii" this comparison is absolutely worthless. The reason I put it here is simply to show that for the price of their console, Nintendo does not use reasonable hardware, which is the same complaint I have with TI.

Quote
The only time price/computing power ratio is a good metric to use when deciding what to buy is if you're putting together a supercomputing cluster.

That's most of the reason I started this spreadsheet. Also, as far as performance goes, neither floating point operations per second nor cycles per second are a great way to compare different processors and architectures.

Quote
For game systems, the value you get is not linear with CPU power or memory
No, but the visual quality of many games is. Crysis 2 would be an excellent example of this, as would Black Ops. For some people, that's all that matters.

Quote
- if you buy ten XBoxes, you have ten times the computing power, but can you really have ten times the fun with them?
Of course not. This list is here only to show that Nintendo uses crappy hardware. Many people don't care about playing Crysis, they'd rather play Bejeweled. For them, the Wii might be the best console, even though in terms of value for hardware, it is lame. I don't look down on people who only play certain games, I just wish Nintendo would use modern hardware instead of being cheap.

I suppose in theory if you could replace the flash chip with a larger one, then you could use the space beyond the filesystem (current boot2's and OSes have hard-coded the filesystem area to end at 32MB, although this may change when OS 3.0 comes out because the CX will have a 128MB flash chip). I don't think there are many of us who could do that, though :p

On the CAS+ nspires replacing the NAND wouldn't be too hard, but for the production nspires you would need some expensive equipment.

Nice big troll above here, mikehill2003...

Nintendo doesn't sell overpriced products. When the DS came out it was about $200 cheaper than the PSP here and the PSP remained above $200 for years until the PSPGo came out. Their Wii costed $279.99 on launch, while the 360 and PS3 costed about $700. Yes, Nintendo consoles are less powerful, but it's totally untrue that their stuff is overpriced. I think that status would go more for other console makers, especially Sony. TI, on the other hand, sells overpriced hardware.

I regret to say that I strongly disagree with the above. I was not trolling/starting a fight. As for Nintento I think that this spreadsheet I made a few month ago explains their position here in the US quite well. For the components included in their products compared to competing products, their stuff is overpriced.



Quote
Also, if you haven't noticed, the rest of the community wants more powerful hardware. Take a look at the interest for the Casio Prizm color calc: TI programmers bought one, something that would never have occured with their previous products, because to everyone, TI was better than Casio. I seriously don't understand why you are so much against a calc with a color screen when you use one mostly for programming and gaming, something where colors are more than welcome. That said, I agree that their products are locked down so much.

I want more powerful hardware as much as everyone else here. I'm definitely not against a color screen (or calculator games), only the fact that now the screen is a lot smaller. Also, I feel they talk far too much about the new color screen. Wouldn't everyone here rather have a full sized color screen and a modern processor? And as far as bashing TI for crappy components, if they were in the above image, the price/performance ratio would be by far the worst of all.

You should stop trying to start fights.
It was never my intent to start a fight.

I just don't like the direction TI is taking with what started out as a tool. Whats next, music playback and facebook integration? Maybe the CX2 will use twitter and Wolfram Alpha? (And lack a trig key and a Pi key)

TI is too much like Nintendo, they make overpriced and locked down products from crappy, outdated components.

Whats the big deal with the CX for education anyway? Math and science don't need a color screen or the ability to load photos. The gameboy emulator, on the other hand....

Out of curiosity, has anyone taken a look at the filesystem formats yet?
Not yet, but it's on my list.


TI didn't use a standard filesystem like FAT, instead they used a proprietary filesystem called Datalight Reliance. This basically means we have to rely on TI's OS code to do file access (making ports of other OS's, such as Linux, somewhat difficult)

I see. Thanks for clearing that up, I guess I'll add that to my list of things that need to be done.

If someone could manage to write some fopen/fread/fwrite for the TI-Nspire's proprietary filesystem, that would certainly be a huge help to any sort of Linux port.

I'm not sure what you mean by this.

What about BASIC? I heard the on-calc language was even harder than the 68K TI-BASIC X.x. A lot of people like TI-84 BASIC due to the fact it'S easy to use. By removing that easefullness, you single out a large load of programmers, like the Nspire did.

I'm pretty sure RPL is HP's idea of BASIC
http://en.wikipedia.org/wiki/RPL_%28programming_language%29

I haven't used it too much, but it isn't really easy to make games on the 50g without using C. It's much more of a tool then the TI calcs. The TI calcs seem to be made for schools and students, hence the pink TI-83s. HP calcs are made more for people who know what they are doing and don't care about much else (which is why there is irda but no wifi, and the lowest-res screen that is still readible), which is kind of sad, because I really prefer RPN.

Though, I've heard programming wise, nothing is better supported than HP calcs... If only THEY were the popular ones...

True, at least in my experience. It was a lot easier to make software for the HP-50g then it was for the TI-89, and I'm still trying to figure out the nspire.

Yeah in Canada I never saw a retail store that sold them, at least not where I live. I think one reason why is that some people find HP calcs too hard to use. I heard they had a processor that could be clocked even higher than the Nspire. It's a shame it never got as popular...

Yeah, it takes a few days to get used to RPN, but once you do, it makes anything else seem tedious and slow. It actually doesn't use RPN by default, but I've yet to meet someone who really knows both and prefers to not use RPN.

As soon as I can get my benchmark to compile properly for the 50g, I'll be able to see if it's more powerful then the nspire. One thing I do know is that it has a LOT less RAM, only 247kb.

Here's something from HP's site:

http://www.hp.com/calculators/resellers/canada.html

I didn't see any in-store retailers in Canada there that sell the 50g.

Nah they no longer sells HP/Casio calcs.

Well that explains it. I guess the greedy stores care more about selling lots of crap then selling quality products at a reasonable price, just like in most of the US.

The funny thing about it is that for math it's way better then the TI-89 Titanium (I own both, so I do know) and also $50 cheaper in stores. If only it had a better screen (It's about as bad as the 84+ emu on the nspire).

Do they sell the HP-50g in Canada? My TI calcs are okay for basic math, but for a serious calculus course nothing can beat the HP-50g.
