Six Reasons to Not Like Google's Nexus One - PC World Business Center
I def agree with the writer that Google should concentrate on the OS and marketplace and leave the hardware/device market to the manufactures and/or carriers.
people have stayed with ATT's horrid network FOR the iPhone....I have many friends that ONLY have ATT because of the iPhone. The people I do know that went Droid did it to have a phone that is as good as the iPhone on a far superior network. Why would someone want a Nexus on ATT...if your going to use the worst carrier available why would you want a phone that isn't unique to that carrier. iPhone junkies will stay with ATT everyone else will either go to Verizon for better service or T-Mobile for better price and about the same level of service.
