I wouldn't mind upgrading from 7 to this. Let's face it...as good as 7 is, it's still essentially the same basic interface layout design as Win95. It would be nice to have a slicker new interface more in line with a hybrid or bridge between tablets and desktops. Win8 just went too drastically far to the tablet side and all but eliminated anything remotely recognizable as a desktop interface. With that said, I'll likely hold off until I see gaming and application benchmark performance comparisons with 7 before making the final decision.
Nobody likes sudden change, especially we of the PC Master Race. But MS didn't care to listen to the people and we the people rebelled. We will be having mice and keyboard peripherals for PCs for many, many years to come (decades perhaps). I remember reading an article in PC Magazine in the late 90s that stated the days of mice and keyboards were numbered with voice recognition and touch screen technology coming. Yep...here we are 15+ years later, still typing on keyboards and moving a mouse around. Just like in the 80s when so-called "visionaries" said offices would eventually be paperless with computers. Hah!
