As luck would have it I have 2 lines, my personal on vzw, and my business on at&t. I'm due for an update from at&t, but not due for a while with vzw after getting the Fascinate on Oct 1st. For me it would come down to this, upgrading my at&t line which is a Blackberry Torch to the Atrix, and then selling my Fascinate and buying a Blackberry to run on vzw's network. I usually roll with a Blackberry, and a smartphone (PDA) on a daily basis. So for me it can work, but I would have to exercise at&t 's 30 day policy hard. My only question would be if at&t has really fixed its network issues, with dropped calls, and sluggish web performance. If it's on par with my Fascinate I'm all for it. However, that would mean passing up vzw's newer 4G network for at&t's somewhat out of nowhere 3G 3.5 upgrade bump. Ahhh, decisions, decisions!
