As I dig deeper and (now that I have it) read more about the Metro UI, I'm more annoyed with its basic premise. The UI is really just a storefront for Metro apps.
That's okay for a content-consumption device, but very annoying for a work device. It's like advertising for third-party products on YouTube videos--okay.
But if I hire a video company to produce, say, training videos for my own company and they plant Coca-Cola ads in them, I'm going to be steamed. I'm feeling pretty much the same way about the Metro UI.
No one is forcing you to use and/or purchase the apps for the Start page. I just unpinned the majority of them and kept a few that I find useful (weather, calendar, mail). I find it the Start page useful for doing my mundane, day-to-day stuff and then switch to the Desktop for creation related duties. It's all about customization and making it work how you want it...I look forward to more applications that are Windows 8 specific.
Windows 8 doesn't get in my way at all, utlizing the corners and keyboard commands makes it quick and more efficient. It took me a couple of weeks to adjust but now that I have I wouldn't want to switch back.
