I would just like to share a different perspective on your point about multitouch — I have several friends who have tried to make Ubuntu their first foray into Linux on a modern "convertible"/ultrabook/whatever with a multitouch screen and run into issues with responsiveness, scaling, etc. Not using Ubuntu myself I don't know how much work is really left here, but multitouch screens should definitely be treated as a first-class citizen of the HID world.
