You say that Windows 8.1 is better than windows 7 while occasionally poking the user in the eye?

I'm not sure nicer file copying is worth being pokes in the eye by Metro. Faster boot and power management sound interesting, but I would really need independent benchmarks before I would trust any such claims. A 5 seconds or less decrease in boot time (like http://www.zdnet.com/windows-8-vs-windows-7-benchmarked_p2-7...) would not be worth it for me. A significant power boost (+10%) for a laptop might be worth being poked in the eye, if said 10% can be gained while I use the computer (ie, not while sleeping/idling/suspended). For desktop however, power management is not really a feature Im looking for.
