If you could download and rent/buy full version games, would you?

Why not? I would definately give it a try.

The system will be quiet as hell, almost no loading screens, Disc can't break etc.

And when you are really hyped for a game, you could start to download at midnight when a game is released. Then go to bed, wake up and play. better than waiting for the stores to open or checking the mail every hour :)
