IMHO, steel>carapace, unless you have armor fashioned from dragon scale or something rediculous like that.

Hope you have a decent camera man.

Misc. Info:
In additon to a key pad the casio class pad 330 has a touch screen, and yes it is 160x240 res .

Hp 50 G Also has a clock function with alarms. Reverse Polish Notation(RPN) LISP is a combination of Reverse polish notation and the LISP programming language. RPN is not a language, just a format for putting in equations (as far as I know).

Nspire's Basic is extremly basic right now, no way to detect key presses yet, disp is the only command that can display stuff.

This took a while to compile, so I hope it is useful.

@Omnimaga: HP's have built in HP BASIC, but if I had to guess I'd say it's their old BASIC being emulated on the ARM processor. One of the two types of ASM it supports(saturn ASM) is emulated and I assume that the BASIC that runs on there is emulated as well. Don't quote me on it though. From what I've read though everything runs faster on the HP 50G than it's early predecessor, (the 48G) so despite the emulation (again I'm not entirely sure about this) it should run fairly fast. In regards to how their BASIC language is sturctured or how advanced it is I'm not sure. I'm still looking into it. =) I will update the first post as I find more info.

I'm looking at it mainly from a programming standpoint. As far as TI's go I have the 83+ BE, 83+ SE, 86, and the 89. Unfortunatley there does not seem to be a whole lot of information available on the HP's, so that makes me wary. I havent checked into casios yet, but I think I will. My internet is acting rather funky tonight though. The Nspire (CAS) looks extremley sexy, but as of yet you cant do alot with it so I'm gonna wait on that one to see what develops.
*edit* Looked into casios, they don't hold any intrest for me. For the 9860 series the screen rez is only slightly larger than that of the ti-86, and the processor is sligtly under 15 MHZ. The Class pad doesnt intrest me at all, as the res is much taller than it is wide, and I just don't care for the design. I can't even find specs for the processor speed on the class pad.

@Liazon: well...

Update the first post with more info as well.

Ahh ok nice. I Can't wait to see more, it looks really fast.
