When I first got my 10 I wasn't over impressed with it, having used the 7 for so long (4 months), but after having it for a few weeks now, I wouldn't go back to the 7.
Don't get me wrong, there's absolutely nothing wrong with the 7, but I now prefer the 10, but I couldn't recommend one over the other, as people choose for totally different reasons. I had an ASUS TRANSFORMER PRIME which was returned and refunded under an RMA, and my 7 was really only a stop-gap until the TRANSFORMER INFINITY was released, but the Nexus 10 was then announced and as I'd had so much fun with the 7, I chose the 10.
My daughter has my 7 so it's still in the family and when I use it, it's like putting an old pair of shoes on, if you know what I mean :-)
Everything is the same on the 7 & 10, apart from the obvious, which is why I frequent these forums so much, trying to assist where I can.
