broz:
Non-programmable: Casio FX-115ES PLUS
Programmable: TI nSpire CX CAS (can compute matrices with complex entries :D)

cdev:
Me too, I have the Radio Shack EC-4014, which is the exact same calculator as the Casio FX115.

Its amazing that it still works! I still have the manual for it too.

I still use the old Casio FX115 I bought way back in the 1980s.

Does multiple base math and is solar powered.

I'd rather have something that handled RPN but the Casio is what I have.

I use the HP Prime.

I have a WP34S (because it's fun), HP35S (nice recent RPN, good for confusing the kids), Casio fx-991ES (because it's like the kids fx-85S they are asked to use at school) and a Casio fx-4200P (because I'm too sentimental to part with it) on my desk. 

I tend to use Excel or Wolfram Alpha.  :-DD
