I've loved the Cingular/AT&T network ever since I got it 1.5 years ago. I'm still skeptical about the EDGE network, even though I have read posts about the network starting to speed up this last day or so.
I've wanted one of these ever since it was announced in January, but considering I just started a new job & want to save up some money, I'm going to hold off for a little while. It's also not a bad idea to let them work out the inevitable kinks out.
