Poor choice, imho. I'm curious what the actual overhead is for people like me. I have 1 account (as in: 1 email address) that is hosted by google apps. I was going to set up an account for one of my other domains, but not for $50/year. (Per account!)
So full snark here, but it was between google apps, and office 365. I chose GA because o my familiarity with it.
But look here, Microsoft's equivalent offering is free: https://domains.live.com/ I wonder what things will look like when we evaluate google apps next year?
