I must say, the migration process was pretty quick and painless:
1. Register an account with Google Apps
2. Add the relevant MX records onto your DNS (which in this case is hosted on my Cloudserver at Rackspace)
3. Logon to your account at Google Apps and activate the E-mail settings
4. You're done!
Now you'll have a fully functional mail system without having to purchase webspace :)
