I am going to keep my small, compact, extra long battery life, ASUS on Windows 7. It is ultra portable and great for
plain old Solitaire.
It is also great for use on the free external Comcast nodes in my area, and in and out of the house.
My new Large and heavy ASUS seems to do well on Windows, folds to a huge tablet, but is not that portable.
I can't drive two cars at the same time, but I can run two computers at the same time.
The many posts above have led me to the two computer, two operating systems conclusion.
