Look. Windows 8 is like classic small block v/s Dohc AMG M156 V8. The newer build has a lot going for it. Why should anyone avoid W8? It is stable, fast like **** and superb on touch devices. It is a two in one, classic and touch OS.
Yeah, but that small block V-8 is stout and built to withstand much higher stresses than any Coke-can Twin-Cam being built today. There's a lot of us old timers that believe in durability and robustness over ketchy features. The performance gains of W8 over W7 are imperceptible to the human eye as to justify the time and resources spent upgrading. There is no stopwatch to measure benchmark units, only digital tools that spew out numbers that are quite meaningless. I'll take your automotive reference one step further to illustrate my point. If you have two top-fuels duking it out for a final and you're standing at the start line, can you honestly tell who got to the end of the 1320 first? No. You need to wait for the lights and the times.
