We've been using an HP Tx 2 Touchsmart Tablet for some time, and even with it's Display measuring in at 12.1 inches, we STILL have problems reading it at times - with complex or long songs needing to be scrolled and zoomed.

I must say, the Tablet IS shared between us (two people) so for a solo artist, I don't think there would be a problem, but my point is, the iPad's screen is 9.7 inches or so - thus too impractical for us.

Pity, as I'm a sucker for Apple Products in general, and if you took away my iPhone, my life would fall apart - lol
