I played with one this weekend. It's pretty cool, but not $600 cool. It's in a weird spot because being "a phone" is only 1/8 of what it does, it's more of a personal data manager with internet that can make calls. It's really fast, slick and well thought out, but $200 too expensive to not have built in GPS. Out of the 10 you could play with, 2 of them were already broken. And as we all know, cell phones break like crazy and you cannot get insurance on these phones so it's a disaster waiting to happen. But the one thing I didn't get to try was calling someone, not because you weren't allowed...but I basically didn't feel like it
