I used the nexus 7 for a few hours and I found the transitions and ease of use difficult. Not as intuitive as the iPad. Playing around and sending content to the TV and it's not as smooth as airplay. I found the actual screen size awkward. I didn't know how to navigate or read pages. Do I place both hands behind the device and use my thumbs to navigate? Or do I place one hand behind the device and use the other hand to drive? Guessing I would quickly get over that with more use, but it was refreshing to try something different...
I'm guessing I have smaller hands (female) which I suppose could make a real difference in how it feels to hold/use the device and is probably at least part of why I find it more comfortable to use than the iPad.
