I have found a site with a list of many of the applications available for Team System. It seams to be updated regularly and should help with some of the v1 shortcomings of team Foundation Server.

I am particularly interested in the TeamPlain web products from DevBiz. The web interface is sorely lacking in TFS, but at least one can develop against the platform extremely easily.
Has anyone used TeamPain?
