Hi, I'm not yet an ipad owner, but I am intrigued and very interested in them. I have lots of PC/Android experience, but no apple/Mac experience. Will I find it easy to use? Or will it be a pretty heavy learning curve? Also, the *SIZE* of the ipad... just seems a little BIG to be carrying in my purse. I have seen the Kindle Fire and that's just a wee bit *small* (at 7"). Is there an ipad size IN BETWEEN... maybe 8 - 8.5 inches or so? For me, that would be juuuust right! Thank you!
