Gmail is weird. I read yesterday about several new features like contact groups, vacation auto-reply, and mobile browsing, but when I went to check them out, I couldn't access any of them on my account. Then this morning, when I was making some changes in another account I have (I use several for various archiving and filtering tasks), the features were there! Back to main Gmail account, refresh... still not there. So it seems Gmail staggers the release of new features across its accounts instead of rolling them out universally. I'm not sure if this is aggravating or really smart (or both?).
