The formfactor of the TF701 (tablet+keyboarddock) is just the USP that makes people choose for this tablet.
When bought without the dock and no need for a keyboard there are more competitors with similar products which you can compare to each other.
Then things like support (updates frequently available), build quality, stability and over all speed are most important.
