I don't understand the Windows 8 hate; it seems so very irrational from someone tech-literate. It's Windows 7 with a more power-efficient and fast-booting kernel, improved Explorer and disk IO system, better task manager and a bunch of other really useful improvements. It's incredibly stable and resource-efficient, and will likely make any system you install it on last longer with the same battery -- far from a "PoS".
It also comes with an app store. You can ignore the store if you'd like, it's just another program you never have to run. How does the presence of this kill the whole OS for you? Did you once feel the same about the inclusion of Spider Solitaire in Windows ME?
You can alt-tab between metro apps and native programs, you can run them in the background, and drag them between displays too. You can leave the Netflix app up on one screen and your 20 non-Metro windows on the other at the same time. Or you could snap it to 1/3rd or 1/2 of the screen, and use the rest for your other windows. Multitasking isn't defeated in any way.
