Promising candidates would seem to be:
Dell Chromebook 11
Asus C300 (if it's ever actually available to the public)
Acer c720p (previous generation chromebook but is still well-spoken of)
That's the one I want.
FYI low wattage CPUs matter immensely in chromebooks because they directly effect battery life which is one of the top-list items on chromebook spec sheets.
I play all non download casinos without problems on my Samsung chromebook.
... the C300 is fanless ....
