You would still have a market of games unsuited to the current crop of mobile devices. You couldn’t run Battlefield, Crysis, Planetside, Assassin’s Creed III, or World of Warcraft on any of today’s tablet or smartphone offerings. There’s simply not enough to processing power.
The only thing I could see happening, if the extinction of the desktop is a certainty, is the birth of dedicated gaming platforms like the PS3, XBox, or Wii. The newest generations of these machines will be on par with the latest the market has to offer. It’s sad that enthusiasts like me will be left in the dustbin of history, but in the grand scheme of computing, this is not surprising. Those who don’t adapt, die.
I hear ya'. I have my original Descent 1 CD that I wish I could still run on something.
