I had the same problem choosing how many GB. Just went with the middle. lol. Really depends on what you want it for. If you are just surfing and pulling up pics, the 16 should be more than adequate. I doubt that is the only thing you will yse it for though. I thought mine was going to be mostly or s hool. HA.
It has been six month and if this was a 16 I would have filled it to almost a fourth already. So I'm glad I got the 32. Also though, I wanted it to last me at least seven years through school... I didn't plan on upgrading for many years...
There is just something about the camera. ?sone pics are ok. Some just seem really fuzzy. While not the best for different reasons, it is no better than my Alias 2 camera which is also crummy...
Battery life is about ten hours, but I'd say with heavy use (like gaming), that is reduced.
I've had a problem with Safari closing for no reason. Apparently you have to clear cookies and history. Spellcheck is horrible, so mine is turned off. Either way you can tell when I'm using the iPad because of missed letters and such.
