Unless you buy a Tablet or Laptop that has one... The Biggest one I ever saw was on an Acer "AIO" Computer, it was about 26" and the Display also housed the hard drives, DVD drives, and everything else. If you really want one, the guy who had that machine, "rented it to own" from someplace, it was a great machine except for the 4 core Atom processor. But the payments were like 25 bucks a month.
