That's very, very cool. Those who don't use Google for email, contacts and calendar may not have the same experience, however. Especially those using Microsoft Exchange, as the Nexus One currently does not support Exchange calendar sync.
Like we said at the beginning, the Nexus One is not a 100 per cent perfect device. There seems to be some sort of problem with the phone having trouble maintaining a 3G connection (not to be confused with an iPhone not being able to maintain ANY connection at times). Google and T-Mobile have both publicly stated that the issue is being investigated and they should have a resolution soon.
Many Nexus One users (we actually didn't think there were that many at this point) are complaining that their new phones constantly bounce back and forth between 2G and 3G without warning. The blogs are all abuzz with complaints.
The best non-explanation we saw was a video showing a Nexus One handling 3G perfectly when it was sitting on a desk but connected to just the 2G network when the user picks up the phone. Know what that means? When the phone is picked-up the guy's hand is blocking the receiving antenna inside the phone.
