As a newbie to BB and this forum, hope I'm not posting in the wrong spot or rehashing old threads that I didn't find...

Can anyone recommend a decent scientific / math calculator for 7100g? Only one I've found appears to require purchase to download (no try-before-buy); 1 or 2 others don't say they'll work with 7100's reduced keyboard. RPN would be nice, but nested ()'s would do.

Also, any extensive units conversion utilities to recommend?
If I had both of these, I could just about leave my palm and my old HP 15C at home! Thanks for any advice.

try BizMathica from Shrunken Head Software. It's expensive and the interface is a bit clunky but it's the best one I know of. Sorry, don't have the URL.
