DBlank - Thanks for your help with installing galculator. It took a while for me (first time using xterm and becomeroot, so I had a steep learning curve) and then had to go and find a more recent version of libglade.

I like the flexibility of galculator, with the different views, etc, but one thing that might make it not suitable for my purposes is the way it handles the constant "e". I often need to insert e into a formula, since I am often exponentiating beta coefficients from regression models (I'm an epidemiology student). There doesn't seem to be a way to insert e into an equation---it appears to just give put the value (2.718...) into the answer box.

MathJinni actually has a button just for "e", which is great for me. I find it annoying on my TI30x that in order to enter "e" you have to hit the 2nd key first (kind of like hitting CAPSLOCK). For that reason alone, I might stick with MathJinni.

It would be great to have a special handwriting input mode that emphasized mathematical terms, but I imagine that is more of a pipedream.

EDIT: By the way, does anyone know if Tim Teulings is a member of InternetTabletTalk? I was thinking of doing a mock-up of some visual design changes to the primary calculator interface (such as enlarging or changing color of "=" button, increasing text size of numerals)
