I really didn't like idea of mixing metro with normal desktop style of work. Now, after two weeks of using it on work and at home, I can just say that it works great - metro doesn't interfere with desktop apps, I'm using them like i did on win7, and win8 is better with regular desktop style of work in every way!
Startup/shutdown speed is also totally awesome, even I basically don't power off my computer, never.
So, now, when there's no much metro style apps, win8 as desktop OS works great, and in about one year when Store fills up, it'll be even better.
Other things I really like that are much improved over win7: HyperV inside OS, ISO Mount, multi-monitor support (taskbar, wallpapers), cloud integration, copy/delete/move dialogs with speed graph, task manager.
