If Windows 10 is anything like Windows, 2, 3, 3.1, 95, Millenium and just about every other version or iteration, it's going to be a buggy mess for awhile. I have Windows 7 which runs pretty good on my kid's laptops and 8.1 on my wife's touchscreen Dell. If not for the touchscreen, I would have gotten rid of 8.1 a long time ago.
Until there is some must-have game or app that requires Windows 10, I'm not touching it.
