Google announced the Nexus One phone today, which is on sale from Google here. My current contract is up, I’m sick of living with Edge, and I don’t want to depend on good enough data coverage for Skype, so I bought one with the T-Mobile plan. As a former iPhone user and soon-to-be-former G1 user, I’m excited about getting a thin and light phone with replaceable battery and a true headphone jack. I’m a huge fan of the trackball in general, so I’m loving that the Nexus One’s trackball doubles as a notification system; however, I do fear I’ll miss the G1’s awesome flip-out keyboard more than “never.” I mostly use my smartphone to email/text/Twitter, so I’m looking forward to speaking email with voice input, multiple Gmail account and Undo support. More Nexus One goodness as I discover it… now, to wait for FedEx.
