love it!! - hehe, i like the forward thinking, use of a stylus clipped on the side! reminds me of a certain sony ericsson smart phone from a few years ago

i think the only way people are gonna beat that post GAD, is to claim the use of an abacus in their infancy

After an early comp sci course where I wrote a stack-based calculator and parser, and then had to do the equivalent while accepting algebraic input, I just can't get over how elegant RPN is. It's just the right representation, at least from a computing standpoint...

Not sure how fun it would be on a graphing unit though, I'm not sure Calculus and trig lend themselves to RPN...

The Curta is a really intriguing device from a design perspective, and apparently really practical too! I've never seen one in person though.

Nice, I have an emulator of the 42S for my palmpilot and my computer it look decent with the proper skin, the default skin is fugly

I also have an HP48 but I don't do any math anymore and it's too large for a everyday calculator.

Among my many calculators is a Monroe desk unit with Nixie tubes, and a rather chunky Sharp using the very early blue fluorescent readout with the half-size zero. I've started on slide rules too. My scanner is loaned out until 11/16/07 so no photos - sorry!

Laz

BTW, that Busicom looks awesome, Duggeh!

I know technically speaking I'm supposed to actually own what I'm showing off, but check out this: a difference engine (i.e. theoretical Victorian Calculator for the unitiated) made entirely out of lego.
