Windows 7 Will Be Officially Called... "Windows 7"
After Millenium, XP, and Vista comes... Windows 7. Yep. Not a lot of imagination in this one. As unexciting as the name is, I'm excited that we're finally starting to talk about it. It's shaping up to be a really nice OS. I can't wait until you all get to experience it.
