@dentaku: This guy's complaints about the touchpad are strictly device-specific (or device driver-specific to be exact). The behavior has nothing to do with Windows 8 itself. On my notebook, about the only gesture that I have is a two-finger swipe to scroll windows.
His rant about not being able to close Metro apps is simply due to ignorance. There are no less than 3 ways to close a Metro app even without the "X" button.
