I'm looking at the MSDN subscription comparison (http://msdn.microsoft.com/en-us/subscriptions/subscriptionschart.aspx) and am a bit confused. Regarding VS2010 Premium and Ultimate: what is the difference between the two? Both offer TFS but only Ultimate comes with Team Explorer. Can you use TFS without Team Explorer?
Ultimate comes with Team Explorer "Eaglestone" - an eclipse plugin. All of the versions offering TFS come with the visual studio Team Explorer.
