Well the whole vista setup is what inspired me to want to use a limited account. Although those messages get annoying they are good for security and like you say "RunAs" could be used. I've decided to stick as an administrator account for now, but I might give it a go in the future.
One service that I have found out needs Local System rights is the AVG7 Update Service, if it is set to Network Serivce it brings up a message about not being able to change files next startup or something along those lines. I'll try to get round to testing the rest later in the week/ at the weekend.
