The world of the convertible notebook has come a long way in just a couple of years, but we seem to have settled in on two basic types of convertible devices. There are the tablet style devices where the display can be removed from the keyboard and used separately, and there are the notebook style devices where the keyboard can be rotated around and under the display in order to act like a tablet. Acer has decided to try something different with the Aspire R 13 which features their Ezel Aero hinge.
