Trust is far and away my highest priority when deciding on online services, and if it isn't yours... well good luck friend, you're going to need it. Your email is likely to be an important part of your life's documentation, containing an awful lot of very personal information. An unscrupulous provider could use it in all sorts of horrible ways - off the top of my head, how about a lucrative employment screening service that lists of how often you've mentioned getting wasted the night before, or throwing a sickie, or dissed a colleague... let alone the value of strategy, customer communications and other immensely valuable commercial conversations. This is why many here refuse to use email services they don't control. I myself use Gmail, because I trust Google. Not because they say "Don't be evil", but because I think they understand how their entire business depends on trust. Compare this to Facebook, for whom privacy seems to be an afterthought. Their business is being badly hurt because they continue to trample over their user's trust. And what about Microsoft? For me, the rorts Microsoft have carried out in the past twenty years (cynically stacking standards organisations with their minions to bulldoze their document format through was the last straw for me) counts them out. I'll never use another MS operating system or online service, end of story. No matter how much better than the competition. So for me, particularly for online services, trust trumps functionality - absolutely.
