Just for giggles I had Win8 RTM on my Acer Aspire One netbook for a while. Due to the screen resolution I couldn't run any of the Apps so the Metro UI was strictly a start screen. I couldn't believe how much the performance improved on the netbook, it was like I had upgraded the processor.The Metro apps definitely don't make sense on a computer with a screen resolution that isn't high enough to allow for side-by-side display of 2 apps (and they shouldn't limit the split screen to just two). You don't want to switch in and out just to see what is going on elsewhere. So on my laptop I use it almost exclusively in desktop mode. But by now I like the new start screen and the settings. And the best thing is how quickly Windows powers down and restarts.
