Excellent. A gem.

Truly excellent. I owned a 48SX and Im upgrading from a 48 emulator. This is a better and absolutely worth the money. To me, killer features are fullscreen stack, variables in matrixes, and the folders. I like how cute, easy-to-use, and well-thought-out it all is. The attention to detail is apparent.
I dont program, but Javascript programmability seems to be the other killer feature. Im waiting to see what people will come up with. The demos are very impressive.
Two things I would love (and make this deserve 6 stars) are: an equation library and an equation writer. I know I could import equation data myself, but Im too lazy to type this all up.
Highly recommended. Check out the website. Theres much more documentation than I ever saw for an app!
