EDIT: I got bored so I installed 8.1 on my netbook. Upgrading to Update 1 now. We'll see if it's any better.
EDIT 2: Well, I wasted four hours and then discovered that no Metro apps support 1024x600. Don't waste your time installing Windows 8 on a netbook, it's only usable in Desktop mode. May as well just install 7. Luckily I didn't wipe my Elementary OS partition. I was able to boot a live cd and restore grub in five minutes.
Only the native Metro apps. Not that it really matters - most of the Metro apps I've tried were just ports of pre-existing Windows applications that have been simplified to work better in a tablet/touch environment. Using Metro and it's native apps is very much like using Android or iOS and their respective apps.
In short, if you want to run Windows 7 (or 8 without Metro) and you need something specific, chances are "there's an app for that"
