AFAIK, the MSDN licenses are the same, but Action Pack has additional requirements.

>The MSDN Professional with Visual Studio subscription seems to be what most of the persons here are using. This one allows the Windows 7 Ultimate 64 bits version as well as the other software bundled in the Action Pack. Is this pretty much the difference between the MSDN Professional with Visual Studio subscription and the Action Pack? There was also a concern about getting the Office suite but I do not think neither one is offering it.

>Some mentioned they got the MSDN Professional with Visual Studio subscription for about 400$. This seems to be a very competitive price. However, there is a big difference between that and the 1100$ at Amazon. There is probably something different in both.
