The overall implementation is great, very usable and not complicated in the least. Im actually quite surprised how well operations are performed in the "cloud". All of the keys on the keyboard have also been optimized to make entry quick and easy, and the figures are surprisingly good given that they are sent to the device from the server and displayed in such a small window.
However, being an electrical engineering student, I use the symbolic equation form a lot, accompanied b the ezplot function, however, any time an "@" symbol is inserted into the command line, the entire app crashes back to the spring board.
With that said, believe this app is one or two updates away from allowing me to leave my laptop at home when heading to school for the day.
I cant wait until it is more stable!
