Much happier. There are definitely still some things about Android that don't "translate" well over to the tablet experience, e.g., the different app sizes are more bothersome on a larger screen. I also just don't need so many screens -- the device is for leisure so I simply don't have as urgent of a need to glance at information.
Luckily, Nova launcher solves many of these little "quirks."
But in terms of form and function, I'm getting used to the smaller device, and I'm happier typing (or swiping!) emails/messages (I love Hangouts on the N7), happier browsing, happier playing games, etc., than I ever was on the iPad 3 (which I sold).
I think I joined the Android tablet world at a good time. Any earlier, I don't think I would've enjoyed it.
This may be a silly question, but do you have to re-buy nova prime on the tablet? I know if it was an ipad you would, but I have never owned an android tablet.
