The ability to add or remove the keyboard is a benefit.
Of course, when you can remove the keyboard it is much more convenient to hold when reading papers and magazines. Or watching videos, or taking notes on the screen. Ever tried browsing on the sofa with a laptop? So a PC with a removable/add-on keyboard is the best of both worlds. And you only need one device, instead of a tablet and a PC.
