Currently testing a new iPad for work. Screen seems too big for what I want. But I am used to using a iPod or a HTC phone. So it could be because I am not used to the size.
For me, on longer periods I prefer the iPad, larger screen, better quality display and I'm used to the apps. For shorter quick stints, the n7 or iPhone for a quick look. The n7 on its own without cellular capability is limiting.
