Thanks for this. I ordered the 4 yesterday; it will be my first ever iPad! Some family members are donating towards it, so after a bit of playing with it it's going to have to go back in the box until Christmas Don't know how I'll resist getting it back out!
I picked one up during the week. Sold my iPad 3 for almost iPad 4 cost. It's faster, but not massively so if you're just browsing and reading. Good upgrade from iPad 2.
