Yeah some of these corrections are annoying. Although on mine, when I type it's, it puts an apostrophe in automatically. Whenever I put a "s" at the end of a handful of words, it puts an apostrophe. (words and puts clearly didn't haha)
I was sitting at lunch with my kids today and mentioned the 7" - my middle child said, before i even finished really, "buy it for me."
HA.
But, it would be a good size for her and her sister to share. They share a Touch right now.
I don't have a desire for the 7" nor does my oldest, we are happy with our current size. I have a Touch to complement it for my more portable needs, and actually, she does too but rarely uses it these days.
Oh and to the original question - i own a 3G and my daughter has a wifi, so 2 in the house.
