I favor the 48GX with several modifications. I have a library that gives me 5 stack lines, but also shows a symbolic representation. In other words, typing "5 6 /" is represented as "5/6" rather than a decimal equivalent. If you multiply that by 2, my calculator maintains the symbolic representation as "(5/6)*2". By retaining values as symbolic representation for as long as possible, when you finally evaluate, it will result in "5/3". This is great for when things cancel out and it allows me to carry precision further since I'm not working with approximations. I can also request the decimal representation at any time. This is what no other calculator app is giving me.

The 50g already does that as it has a built in CAS so symbolic is default. This are represented in their rational form or with respect to pi. 50g is basically a 48GX emulator with 400MHz ARM core that emulates Saturn, MetaKernel and a CAS. Goes like lightning. Oh and a bigger screen so you get 7-9 stack lines. Also you can use SD cards as ports. Mine has 256Mb of Flash. Eats a set of batteries once a month but it's worth it for the power. I can create a symbolic list with 50,000 entries in quite happily on the device then do all standard two-variable stats on it in 1-2 seconds.
