Fastest selling, sure, but still selling far less than it could if there were more to buy! I have been trying to find one but it wasn't until I by pure luck got one of 5000 units that were sold out in 4 minutes. That was last week! If I remember the numbers I've seen correctly then the PS5 outsold the previous quarterly record (PS4 launch) in two months while most buyers couldn't find one. It's insane.
It is a nice piece of tech. I have two big slow-moving fans in my cabinet to make my PS4 shut up but now I can hear them instead of the console. I have yet to hear the actual console even though I'm playing 4K@60 and 120hz games.
