HP seems to be making the argument, that if it can't sell gaming PC's, then gaming must be dead, or something...its all straws.
The market isn't going to suddenly shift to consoles and not PC's like a snap of your fingers. Look at VHS! The last major VHS distributor closed shop, and VHS format has been around for almost 32 years, DVD format debuted in 1993, and we're only now phasing out production on VHS.
But the DVD replaces the VHS, here's the biggest difference. Console gaming doesn't replace PC gaming and vice versa, both methods can coexist just fine. And even with all the home gaming around, places like Gameworks thrive on their arcades. Arcade gaming will die before anything IMHO
