An additional data point to the other commenters: I switched to Fastmail a few months ago, and I am extremely happy with it. IMAP is much faster (especially search). I love the Sieve support and the domain hosting, and beyond that, Fastmail has all the features I need. The only downside so far is that the spam filtering is not quite as good as Gmail's. Even spam identical to stuff I have marked as spam keeps reappearing. But it's not bad enough to be annoying.
