This is how a felt the last two weeks learning how to use Google Apps. Every time I work with Name Servers or DNS settingsI feel like sticking my head into the monitor. Sure most end users are polite and curious as they realize that changing their hosting company can take some time and getting used to new software might take some time. The main reason I have been moving companies over to Google apps is because a lot more people are getting data phones and want to be able to read their email on the Android. Mobile Email reminds me of when the cell towers came to this area in 1998. It is great for communication, but a lot of the early adopters just say "Can you hear me now?"
