Google apps - cheap alternative to mail server upgrade

This is sort of old news, but still worth mentioning as it doesn't seem to be very popular at the moment.
Do you have a cheap, modest hosting and do you like gmail? If yes, then you will love this:
Google offers a free Google apps membership for "families and groups". What's the catch? Well, you can keep your cheap hosting but use the a google email server, with a 2 GB mailbox and all the features of a gmail-like webmail on top, for free. All you need to do is sign up and then change your MX records with your host's DNS (they will probably do that for you, most hosts do because at the end of the day it only means less traffic on their server).
I no longer use this because I got a better webhost this year, but I tried it and I loved it.
