Unlike its biggest competitor, the Sony Playstation 4 ($400) isn't a one-room-entertainment system. Sure, it has all the things we expect from a next-generation console: a blazing-fast processor, lots of memory, and killer graphics (thanks to an 8-core x86 chip and 8 GB of GDDR5 RAM). And it has all the video services you'd expect, though it won't connect to your cable, or respond to gestures and voice commands. But it does have something, in addition to the cheaper price point, that Playstation fans and maybe some converts will love. Sony places none of the restrictions on used games that its competitor enforces, and it doesn't require you to be online to play. We like that a lot.
