Someone buying a 10-20 games over a lifetime does not make them technically astute. But it could mean they will run out of space, especially if there are more 4-5gb installs in the future.
Its not that its difficult for people to uninstall a game when prompted, its just that if you have 3-4 games that require big installs not installed due to space. Then every time you want to play them it could take 10 minutes to start a game.
I doubt the 20gb owners were told or ever expected that there would be installs of 5gb or more for a single game. The fact that there are few of them doesn't make it good... So why should a 20gb owner *have* to upgrade his/her console or suffer waiting for things to install all the time? That seems unfair from Sony... Especially considering that a 20gb owner is probably on average quite a big PS fan.
Tease.
