Returned my Asus 900 for an Asus 901 and then returned that for my Dell.
No moving parts
Slimmer, nicer design
And, I liked that were less keys and that the function keys are gone. The simpler, lesser keys design, no moving parts help keep this the simple "go between" device that I want this to be. I don't want a full blown tiny computer...just something that fills the gap between my desktop at work and home.
The biggest thing for me from the Asus too was the single large 16gb SSD
. With the Asus, the 4gb was annoying to have to deal with. I spent more time overcoming that than I spent setting up the Dell completely. And I don't have to worry about it any longer either everytime I want to install something.
