A lot of people here are suggesting moving from one closed ecosystem (Google) to another. Unless you are really moving to a fully open source alternative which has all - email, calendar, cloud storage, may be a browser and an integrated smartphone etc. I don't see much point behind doing that, especially since Google doesn't have much track record of "misusing" your data in practical terms (that I know of at east). The only FOSS organization which is capable of doing and promoting it on a large scale looks like Mozilla. They already have a few of those, and a Firefox OS phone is coming as well. Mozilla guys, are you listening?
