The remote keyboard is too small and cumbersome.,  It has communications problems due to the location of the sensor behind the screen.  The keyboard adds to this by having keys too small and too close together.  I constantly click two keys at the same time.  There was no DVD drive for the input of my programs from a CD/DVD, and had to purchase one.  No means of backup DVD.  Had to add a hard drive also for my collection of pictures(my hobby).  The Microsoft Office 360 would not run and had to be uninstalled.
