I know someone who might be willing to sell me a TI calculator with a QWERTY keyboard, but they are not sure weather it is a 92 or a 200. I am thinking of buying it so that i can say i have one, but i already have the TI-nspire CX CAS and i do not know if it is worth it. Any suggestions?
another unrelated question, is anyone thinking of making a web browser for the CX using the TI navigator wifi attachment? that would be really cool.

If you get a 68K calc, please keep your other calculator too. The 68K is very nice for games and programming, but almost nobody use them in the TI community anymore, so if you start making games for it, almost nobody will reply to your topics nor download them. However if you don't plan to sell your other models, it's a good idea to get a 68K too. Make sure to get a TI-89, 89T, 92+ or v200, though, not a 92. The old 92 with no Flash memory cannot run any 89/92+/v200-compatible games.

However they're really much better for programming in the way that TI-BASIC is not as limited (and is better than 83+ BASIC for some stuff) and you don't need stuff like Ndless to run ASM/C programs. Also 68K calcs are already much more documented than TI-Nspires for programming. There's no Lua I think, though.

Anyone want to say anything about a web browser for the nspire?
I know they made a web browser for the 84 that had to be plugged into a computer with internet.
It would be really cool if there as one made for the nspire that need no computer.

If some would reverse engineer the Nspire wifi dongle (that means the person has to have one), you could make a browser using Ndless.
But the dongle's are very expensive and hardly anyone here has the time to do something like this.
If the USB protocol was figured out, using normal wifi dongles might work. But then again extremely much work must be put in it.

Unless there is someone willing to spend hours and hours on this, there is not much chance that it will happen
