While not as big of an issue as not having backwards compatibility or some other omitted features of the Xbox One, Senior director of product management and planning for Xbox, Albert Panello, revealed that the Xbox One doesn’t support vertical orientation.
“We don’t support vertical orientation; do it at your own risk,” Panello told Gamespot at the Tokyo Game Show. “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.”
Panello also noted that Microsoft discovered that most people all ready have their Xbox 360 horizontally anyways.
“We found, interestingly enough,” he added, “that 80 percent of people, believe it or not, have their Xbox  horizontally.”
So, I’ve always keep my Xbox 360 vertical. I just assumed that was the way it was suppose to because it looked like it was built that way; it has the hard drive up top and how you insert the controllers just made it seemed like it was better suited for standing up. Mind you, I still have the older model 360 that sounds like it is going to blow any second. I guess that puts me in the 20%, and if you are also in that 20% then leave a comment so I don’t feel so alone.
