I'm mainly worried about hardware support. It would be nice if external USB peripherals were supported, and proprietary drivers don't run on ARM.

I think the idea was to build two, one arm, one z80, for both product lines.
ARM Cpus will almost always be better than x86 CPUs power-wise. An energy-effecient x86 CPU compared to a rather poor ARM will measure about equally. x86 focuses on backwards compatibility, so it's software is compatible across models. This also makes it very complicated and inefficient. ARM is one of the best (if not the best) CPUs for portable devices. Ultra-low power x86s are just really really weak, particularly efficient (for x86) CPUs. We can get a much more powerful ARM for less cost.
If we do use an accelerometer, can we at least use a Tuning Fork gyroscope with it? (They're in the Wii motion Plus) An accelerometer by itself is much more innacurate, and it shouldn't cost too much more.
Why not use a USB OTG port? They're very common, and fit both mini-A and mini-B cables, mini-A being for acting as a storage device, and B for acting as a host. They;re on the 84+, btw, as well as the 89T and nspire.
But x86 also brings with it compatibility with existing hardware drivers, and more software. And it would be able to run Windows. Who doesn't want Windows on a calc?

A touchscreen would be nice, although it would mean instant banning on all College Board tests.
From what I see in the first post, this sounds more like a laptop pretending to be a calculator than a calculator that's nearly as powerful as a laptop.
Linux would be wonderful, since then we'd have the massive pool of Linux software to draw on.
Is there any reason why this is ARM instead of x86? There are several ultra-low-power, low cost x86 CPUs in existence.

Schools will not buy armies of rechargeable batteries, so we should just pretend they do not exist.
Wait, we're marketing this to schools, not users?

I voted 50 Mhz, since speed is good and if you use rechargeable batteries, battery cost is really not an issue.

While we're talking about animations, would it be hard to make the little man move smoothly from one block to the next?

I like it!
Although the explosions could use a little grayscale...

That is a good idea. I presume Ndless supports such things at the moment, despite the lack of a program loader?

Mmm...bombs! Nice work

Excellent! This is certainly useful for people who want to edit more than 7 lines of text at a time

A bugfix update: the program now calls free() appropriately at the end of main() to free the malloc'd blocks of memory. This should prevent some random crashes I've been getting. Also, attached some screenies. We all love screenies, right?

Darn, I just lost too.
Congrats on Omni being alive and well again!

Hmmm...you can never go wrong with MIT, which is where I'll be headed in a month. However, it is rather expensive (~$46,000 a year  ), not to mention a pain to get into.
