This install stuff really is such a non-issue.
The missus just got Everybody's Golf on the PS3 (she loved the playable demo from PSN) It had a install time of approx 15mins. Guess what, she spent 15mins to get a cuppa and sit down and read the game manual. End result - during the game there is hardly any load time what so ever. Sounds fine to me.
Why do people complain? Do they buy games to spend the time playing, or spend all day installing/uninstalling/installing.... lol
Like others above have said - most have a larger disk now days anyway (250gb here as well)
