It depends on what you're looking for :
A portable reader?
A portable media device?
A portable gaming system?
A GPS?
A handy dandy word processor?
The best hint I can give is try free stuff from the PlayStore... There's a lot of it.
I use mine for everything from moderating forums to, shopping, email, reading, watching TVs/movies.
My cable company even has an app to control my set top box.
Basically explore and enjoy.
Any specific questions on an app or function, ask away... :thumbup:
