Windows 7 looks really good. I had the beta dual-booting with XP on my old computer and it runs faster than XP, even with all the special effects turned on!
And for those of you who say that Microsoft “copied” the dock from Mac OS, I agree, but look at how much Apple copied from Microsoft, such as Intel Processors, an office suite, USB compatibility, you may even say they based the dock off the MS taskbar (because Mac OS 9 had no sort of taskbar or dock).
Vista was a complete flop. Very slow and I think they need to tone down the glossy effects. Can’t wait for 7 to come out!
