Thanks for the version info. Sounds like they are continuing the separate editions like Vista. Why not just release one version and call it Windows 7, and leave it at that. Or Windows 7 Enterprise / Professional for business, and then Windows 7 for the rest of us.
When my friends where asking me about Vista when I used the RC1, they said they felt misled because they wanted the eye candy and then purchased the wrong version. Why all the separation? Is there any real reason that I am not think of?
Just my opinion here: If you need new hardware, a large HD, better graphics card to upgrade to the new OS, why not just have one version and tell people in plain english these are the requirments to run it. sounds logical, but that makes to much sense.
When Vista launched officially I read lots of complaints about the different versions offered and many, many people felt like one for regular people, and one for business would be the best way to go. MS should do that with Windows 7.
