There are 3 primary ways to play games. In a computer chair staring at medium sized screen, in a couch staring at a big screen, or anywhere staring at a small screen. The question is are you a PC, console, or mobile gamer? Cloud or stream gaming might be able to change what you consider yourself.
The thing about this type of gaming is that the medium you are playing your game on doesn't need to be capable of processing the game. It's similar to how if you watched someone streaming a game on twitch.tv you wouldn't have to have able to run that game yourself.
Sony had their big announcement of Playstation Now recently and while the information is limited, it's all very promising. The premise is that you can stream Playstation's library of games on various devices that might not be able to run them otherwise. It is poised to start on Playstation 3 and 4 but will make it's way to the Vita, smart televisions, even tablets and smart phones. This means that you could play The Last of Us on the subway or Grand Theft Auto 5 while waiting at the dentist. This will also allow all those Playstation 4 owners who have little to play to soon get their hands of a vast library of Playstation classics. Playstation Now is slated to come out this summer.
Valve also has their hand in this technology and have just sent out more beta invites for their In Home Streaming technology. It's similar in many ways but unlike Playstation Now, you still need to have a computer capable of running the game you wish to play. This may seem to defeat the purpose but this is intended to allow people to open up their entire house to PC gaming instead of being limited to the spot where they keep their gaming capable computer. This may fill a similar role as the Steam Machine in that it will allow you to play PC games in your living room.
This technology isn't new as OnLive has been allowing this kind of service for years but Valve and Sony seem confident that they can make it work for them. Whichever interests you more, it's likely that this technology will become more prevalent with time.
