||Devoted fans of specific games will base their buying decision on which console offers them.
||Installing a game on your system's hard drive can reduce its loading time, because information isn't being pulled from a disc. But the games also take up space on your hard drive. The PlayStation 4 requires you to install at least a portion of the game before you start playing. The Xbox One requires you to install the game, but you'll still need to have the game disc in the tray to play it.
||Game play, streaming-video services (Netflix, Hulu Plus, etc.), Web browser, exclusive access to Sony Video and Music Unlimited, planned exclusive content from Sony Pictures.
||Game play, Streaming video services (Netflix, Hulu Plus, HBO GO, etc.), Web browser (internet explorer), exclusive NFL access, planned exclusive shows like a live action Halo series.
||A PlayStation Plus account ($50 a year) is required to play games online, but access to most entertainment services will be free. An Xbox Live Gold membership ($60) is required for most Xbox One features. The Xbox One will have more entertainment options available at launch, including HBO Go and an exclusive deal with the NFL. Access to streaming services can change over time, though, and both consoles expect expand their entertainment options.
||Play as you download, streaming game play, game-save storage, streaming from PS4 to PS Vita
||Play as you download, game-save storage, cloud processing (which adds to the processing power of the console itself)
||The use of the cloud for both consoles will evolve over time. For now, both consoles will let you play while your game is still downloading, and both will store saved games in the cloud. Sony has announced it will have a library of PlayStation One and Two games available to stream, as well as the ability to stream games to the PlayStation Vita from the PlayStation 4. Microsoft plans to use the cloud to provide additional processing power for games, provided you have an Internet connection, which could minimize the difference between the built-in processing power of the two consoles.
||Using the Xbox SmartGlass or PlayStation app, you can see what games friends are playing, send messages, and check out their achievements and trophies. You can also use second-screen features such as maps and some control of the console. You can also purchase games and download them to your console via the apps.
