Microsoft has issued a warning to prospective Xbox One owners: don't stand it up vertically!
Do so at your own risk, Albert Panello, senior director of product management and planning at Xbox, told GameSpot at the Tokyo Game Show.
"We don't support vertical orientation; do it at your own risk," he warned.
Then, he clarified: "It wouldn't be a cooling problem, we just didn't design the drive for vertical. Because it's a slot loading drive, we just didn't design it for both."
The Xbox 360 is perfectly happy positioned horizontally as it is vertically, of course. But according to Panello, only 20 per cent position their current-gen Xbox vertically.
"We found, interestingly enough, that 80 per cent of people, believe it or not, have their Xbox  horizontally," he said.
I'm part of the 20 per cent, then. Are you?
