Windows Vista service pack 1 has nothing significant for consumers

It seems that service packs are mainly rolled out for security purposes
Microsoft's Pete McKiernan, a senior product manager for Windows, told CNET News.com that one of the purposes of a service pack is to include all the patches that have been released in one package. Windows Vista SP1 will have that, but little else for the home user

I think it's good that they are releasing  a service pack so soon and not waiting for the next security disaster
