My Initial Windows 8 Thoughts

I've been playing with Windows 8 for about an hour now and I still don't know what it is.  Is it Windows 7?  Is it a tablet app on my pc? 

It seems very disjointed.  Who cares that there is no 'Start' menu, I just want to know how I should use this thing.  The tiles and everything are very cool, but why do I have two versions of IE?  One in the tile mode and one in Windows 7 mode...very odd.

The whole thing is just ODD.  More to come...
