Still in the first week with my Nexus One on AT&T (too many family members to leave, and in the DFW metroplex here in TX the network is pretty good). I started my smartphone life with RIM and the 7290 (I think) and stayed with RIM for a good 3-4 years while working for IBM and using the IBM purchased phones . Went to the iPhone after I left IBM, and stayed with it until the Nexus One was available for AT&T's 3G network. I have a programming background, and am now working on the system engineering side of the house. Not planning to actually develop anything for the phone, but I like the idea of being able to if I get some grand idea. But, I do love to mess around with my phone, and will enjoy learning from the experiences of those on the forums... Thanks!
