I haven't been on Omnimaga since last year so I'm pretty out of the loop in terms of development. I just bought a new TI Nspire CX CAS. I was wondering what I should do with it? Downgrade? Install Ndless? In terms of aims, I'm mainly looking to make the Nspire as useful as possible (possibly instead some programs, games, etc.). Anyway, any advice would be incredibly useful!
