I just got a G1 last week and my major complaint is needing an adapter to use the headphones/headset. The ringer also doesn't seem to get very loud. I haven't had time to load extra audio so this might not be an issue.

After I've used the phone for a month I'm going to look into running custom Android builds that enable multi touch and other features.


Also the future Android phones/devices are NICE.
