Let's agree to disagree then
it's never sound advice to turn off security features (all imo ofcourse!). You wouldn't listen to somebody who'd say "it's a nice neighbourhood, you don't have to lock your doors", at least I wouldn't.
I agree it's annoying at best, but it prevents abuse by trojans and the like and user initiated "accidental software installation" (i.e. Incredimail on corporate PC's >.<).
It also prevents legacy applications installing as well as any Vista application that may not call administration permissions the Vista way. I've had graphics drivers fail to install due to UAM and I know one of our applications here installs on Vista fine if you switch it off as you get proper admin rights to install DLLs rather than having to call for them through a remote application.
UAM is Microsoft's attempt to replicate Linux et al's call for root permissions to install applications but it's been implemented badly and as such applications granted those permissions can still fail to install.
