Love the phone but after spending a few days with the Nexus one, here are the Top 5 bugs that are driving me crazy at the moment: #1) Chaotic switching between 3G and Edge even when strong 3G signal is available. #2) Attempted automatic Cellular data to WiFi hand-off results in "connection unsuccessful" until connection is manually forced. #3) Poor Exchange server integration - slow resolution with server; no Corporate calendar; unable to move messages to sub-folders without 3rd Party application such as Touchdown. #4) Poor battery performance #5) Cellular data connection takes a long time to come back up after extended period of no service (i.e. long subway ride) and requires switching Airplane mode on/off to resolve.
