It being in my GMail account is handy. Like, if I sync my x@gmail.com depending on the software I'm using all my contacts, calendars, tasks, etc are synced.

I do feel like a whore of the 'tasks' world going from one solution to another. Recently, it was teuxdeux > todoist > thinkery (My current 'lover'). I wish someone could combine them all -- that's actually a 'sometime in the future' personal project of mine.
