Besides gmail's superior spam filtering, this is the one thing I miss from google.

I look around once in awhile, and I never do find a good solution. My current solution is Thunderbird's Lightning extension, and I cringe every time Thunderbird updates, which is often now that Mozilla has the constant update fetish.

I would love to find a reasonably priced calendar solution with a company that I believe will be around for at least five years.

I really wish fastmail did calendars. Are you listening FM?
