i played a long time on my iPod till i bought a iPad
i thought i never would play ona big thing like the iPad but after 1monht i loved to play on it, i have now over a year my iPad 2 and i works really fine, no lag, long batterie (7h-8h graal playing. on my iPod 3 it was only 1-3hours), you can see more than the ipod noobs
I never will play again on a litle thing like the ipod/iphone
