^ I agree. I do not like the 2D approach they've taken. GPU's and CPU's are plenty powerful enough for the devices that will be running W8, that we can have a little eye candy. I'm using Aero on Vista and W7, and I don't find it laggy.
The thing is, some folks have done their own personal shoot-out tests pitting W7 vs. W8 and found that W8 runs a little smoother/faster in some cases. With a W7 theme mod on W8, you should be all set to go. But that is, like Deacon White said, if you really need to get a new operating system. For an existing computer, W7 is more than enough for most people. If you have a large tablet device, well then W8 is probably the better choice.
