Is 3D graphing still on HP's Prime to-do list?

[Parmenedes]

Thanks for the input, Dale.

A new question: As I've been exploring the Prime, I noticed that I'm getting a syntax error when copy/pasting an expression from the CAS to the advanced graphing app. Specifically, I differentiated the function (1-x^3)/(1+x^4) in CAS, then tried to copy/paste the derivative (which is a pretty lengthy expression) into the advanced graphing app. Every time I hit the enter key, I'd get a syntax error. I tried it with and without tick marks as well as with and without "y=". Any idea why it's doing that and how to fix it?
