Not necessarily pointless
Just because you can afford a desktop gaming rig, that doesn't mean it's the best option. I hated moving a desktop between home and university at the start and end of every term, so by the 2nd year I had switched to a high-end laptop, even though it generally sat on my desk for eight weeks at a time.
Similarly, for the business traveler with a gaming habit, this looks like just the ticket - ample power for a spot of Oblivion in a hotel room, and fits fine in a wheely suitcase, unlike a desktop plus monitor.
The only question is how to claim it as a legitimate business expense... :-)
