Ed Hintz has started blogging with a post that describes some of the differences between working with SourceSafe and working with TFS.  Ed's the dev lead for the source control client team and is the person to whom I report.  So, check it out and be sure to let him know about the things you do and don't like in the TFS source control integration for VS 2005.  Your feedback will not likely change v1 at this point, but if you want to influence the next release, now is the time to speak up.
