"Better than Expected"5.0 starson by grgnv
Pros: F A S T, great display and it has plenty of room for apps.
Cons: Bottom buttons are a bit tricky and no blue tooth voice dialing.
Summary: I migrated from the G1 to the Nexus One. Couldn't be easier. I was able to keep my cheap family voice plan, and there is no cost difference between the G1 data plan and the Android data plan, so my monthly bill is the same (conversion took minutes even though T-Mobile quoted 2-48 hrs). All the apps I purchased on the G1 showed up as purchased on the Nexus One and downloaded and installed effortlessly. The OS is more polished moving from Android 1.6 to 2.1. It is lightning fast compared to the G1 and everything just seems to work better and faster.
Overall, a great phone and a significant improvement over my beloved G1.
