Well, that's about it. It's heavier, thicker, slower, and the battery life is really bad (2-3 hours).
I'm curious what you are running on your tablet. I use my Nexus 7 on a daily basis. The battery life isn't great, but I can stream music over wifi to a bluetooth speaker for 5-6 hours a day at work and still have enough battery to play games, read books, surf the web, etc. for another couple hours at lunch and at home.
Further, no matter what Google wants you to believe, Android is notably harder to use than iOS.
How, exactly, is it "harder to use"? My 5 year old daughter has no problem finding games and playing them on any Android device she's used (straight Android, Samsung, Kindle, etc.) and can easily use the search functions to find videos or more apps. I know she's smart, but I would assume most adults are at least similarly capable.
