The PS3 uses cloud save storage if you are a PS+ member.

me too bud, i dont like the idea of cloud gaming, look at onlive, i perchased the latest dirt game from there for £40 and in the small print it basically said that id have access to the game till like 2014 or something to that effect. plus if a device ever goes bankrupt that offers cloud gaming u loose all your games, at least with a hard copy its yours forever if u so wish

lol

its not cloud gaming, its cloud storage.

you can save your save files to the cloud, along with your profile. you cant play games from the cloud. its awesome, it means you can play a game at your house, then go over a mates place and pick up from where you left off without having to take a memory card.

and its not like the PS3s horrible way of doing it. you simply say to save to the cloud, and you dont have to keep going in to your save data folder and uploading each file.

But you could be wrong too.
For instance, Apple initially chose the cloud to deliver it's OS X Lion isntead of DVDs. This resulted in a brand new OS that was available for 29$. A lot of people did raise hell, which resulted in OSs being available in hard copy for 69$. They said that not only the hardcopy material costs, but shipping it from factories bump up the cost a lot. And this is the only hw that Apple makes available without 'Apple tax'.

Regarding the fact that "you won't own it", that's wrong too.
When you get OS X from the cloud you can download it again and again from the app store. It also allows you to install to multiple systems as long as you have your apple id on that Mac.
