... But those OSs (DOS, Windows 3.1, Windows 9x, MacOS earlier than OS X) are all dead and gone now. Linux (and other open Unix-like OSs) continue to move ahead, despite not making a fortune. And while a lot of that is due to their open nature, much is also due to their not being tied to any particular architecture -- various machines come and go, but these OSs continue to adapt to new devices while still being able to run their standard software. tl;dr: No need to wait for a geek tablet to come out, or to worry about how much geeks squabble with each other; every tablet is a geek tablet, so long as you can get an open OS onto it.
