I just got my 64gb Wifi yesterday and my wife is already thinking she may want one too! I told here if we did we should get the 16 3G+Wifi and pay for one Ipad to have 3G for when traveling. How do other people do that in a 2 Ipad family?
Wife and I each have a 16 WIFI, had so for 3 months.... I hacked her Palm (now HP) Pre and my iPhone 3G and when we need it we tether the iPads to the phones and get 3G.....
Gonna wait till the next generation before we buy a second iPad. Of course, I said that with the Kindle and wound up buying a second one three days after the first was delivered.
I bought a 64Gb 3G+WiFi on launch, my wife when I was buying it, was so so about it, thought it was just another gadget. Then she had a play with it and started to really like it, she wouldn't give it back most of the time. Two weeks ago was our anniversary and guess what she got from me as a present........a 32Gb 3G+WiFi iPad.
