I find that holding a charge is pretty rubbish compared to the ipad,it can be slow to go from portrait to landscape and it does not seem to hold a decent Wi-Fi signal as well as the pad. But and this is a big but it was a damn sight cheaper than the ipad so that is a massive bonus.
On a personal note I am not sure I like the smaller screen but in saying that it does make it more convenient to carry.
One thing I have noticed is that using Google drive the Nexus 7 syncs far better/quicker/easier than the iCloud which I had so many problems with. Another plus is that your apps are stored in the cloud so easier to transfer to another device, I don't think itunes/Apple made this very easy at all.
