I haven't googled this yet to see if the problem is profound, but I just noticed something today about Sony's PS3. First, any time there's a Best Buy, Circuit City, or other similar store, I wander in. 99% of the time I don't buy anything, but I just enjoy being around the gadgetry. You understand.
So, I've made it a point to look/try the PS3 demos that each store has. And you know what I've noticed? All except once, the PS3 was locked up. I'm not saying there's a design flaw or anything, but I have noticed this in multiple stores. Maybe it's just not made to be locked up, I dunno.
