I’m trying not to repost other articles but I think this post from Brian Harry is worth highlighting: Team Explorer Everywhere 2010 SP1 is now available to MSDN subscribers. There are some interesting new features here including the capability to install Team Explorer Everywhere into an Eclipse Platform Runtime Binary, essentially providing a stand-alone client on non-windows platforms without needing full blown Eclipse (analogous to the stand-alone Team Explorer install).

There are also workspace switching and source control explorer improvements as well.

Cheers,
Giles
