The 802.11n is a fast wifi that is good for people like me will likely never connect it to AT&T service. The data plan for this with AT&T is 29.95 per month and no cap. Much less, price for 250 Mb cap. It was unclear from the presentation if you might need an external USB dongle for the AT&T GSM service but the wifi is built in. They pictured one but I'd need to review the presentation again to recall accurately.
Video- with exception of Flash, it does everything that iphone does. They showed it playing some movie download. ( Star Trek ) Someone explain why Apple doesn't do Flash???
Geronimo- I agree with you about Verizon and the 4G version. In the meantime, if someone really wanted Verizon data service with the ipad, just go to Verizon and buy a mifi. It's small and will get you Verizon 3G to the ipad, your iphone, your macbook etc. Today, Verizon gives you this option.
I was hoping for a demo using video skype with a built in front facing camera. Video skype is a great app for ipad, I think.
