Downloaded and installed the "Developers Preview" of Win 8 last night. Remember this is a pre-beta release, and for certain it's in it's infancy relatively speaking. As of this moment in time, Android has a much smoother interface for touch. Win 8 still feels a bit sticky for lack of a better word. I installed it on my HP Touchsmart TM2 2150 US laptop (core i3 with 8Gb ram), so it's not exactly a slouch in terms of hardware. It's a total touch screen laptop that has a screen that folds down onto the keyboard to create a tablet. As of this moment, Win 7 has a much better touch screen experience, but I fully expect that to change as the builds mature.
There are very few apps that come with it (28 I believe), and no app store as of yet obviously.
I read last night that typical Windows apps will not run on the ARM version of Win 8, and that MS is going to do it's best to prevent side loading of apps on the ARM version to keep people purchasing apps, instead of loading them from a USB stick or SD card, but that is just rumor as of right now.
Long story short, you're not missing much yet.
