There is no longer a free tier for FastMail.
As I mention in my post, Google Apps is a lot of overhead for just email. There are additional complexities with switching from gmail to google apps because of the integration with all other google services.
If someone was interested in switching from gmail to a paid service, I would argue that FastMail may be a better choice than Google Apps.
To those who are arguing about advertisements not showing up in the Fastmail's paid tiers should also realize that there is the Google Apps for Business accounts, where you don't see ads. It also beats the popular 'if you are paying you are the product meme'.
