This. Also, if you use Google Apps for Business then it's only $50 per year and you get a dedicated, 24/7 support phone number you can call.

Seriously, Gmail is free, you really can't complain about something that's free (yes, I know you "pay" by looking at ads, but when you can upgrade to the "premium" service for $50, never have to look at another ad again and get 24/7 phone support, why wouldn't you?)
