- Play Music: sounds files in Alarms, Notifications and Ringtones are now show in the library. This wasn't before.
- Google+ 4.2 initial release: Had only Android 2.2 and 2.3 checked as compatible versions.
- Hangouts: Didn't work with tablets. Does not have Google Voice features included but removes that ability when you upgrade to Hangouts in Gmail.
- Google+ website: Minor things like the share box when typing. The reply button only working when you haven't clicked in the comment box. No option for auto refresh. Notification box marking all messages read despite having only read 3 out of 7.
- Latitude: Report from this device box unticked for no reason.
One thing I've learned from my work is that a lot of people don't know the stories behind some decisions. But getting it explained can call a halt to any confusion. Not everybody will accept it but at least they heard the reason.
