I switched a few weeks ago. The process was fine. They have a tool to help you port your mailbox, calendar, contacts. The web client is great. The mobile/android app sucks. The search doesn't work. If you archive an email on web, it wont always apply to the app. The sync between clients is screwy. Gmail is no doubt a better email product but given I paid a year, I'm going to suck it up and deal with it.
