Y'all probably already know how I feel about the bifrucated Windows 8 UX (those perspectives were shared publicly during my original experience with the first public developer preview).
You've also probably seen my dad's Windows 8 video, underscoring my belief that this release is going to frustrate average users.
Seems that many pundits are in agreement with me; this thing is trying to be all things to all people on all possible hardware configurations and may very well appease nobody at the same time.
Is Windows 8 optimized for the desktop or touchscreen? "Both" as an answer is a disaster in the making.
