They are different target oses.
8 is clearly not a multitasking os, the UI focuses on one application at a time. It isn't necessarily a bad thing, it matches a tipical use of a tablet, for example. If you want to multitask, the desktop is still there, but it's not the main focus.
If on the other hand you need to do complex work, just go with traditional Win7.
I presonally think they both will live side-by-side and happily ever after.
Or just switch to Mint/Android.
