For some time now, it has boggled my mind why so many people request this feature and get upset when said game does not work using discless mode. I don't see the problem. You put a game in (one game, any game) and leave it there. Job done!
Now don't give me some lame excuse like you're lazy. You had to do so much work turning on the damn machine;
1. Press power button on console/press PS button on controller
2. Turn on TV
3. Turn on sound system (if relevant)
4. Sit down
So many steps, how could God expect you to invest the energy into giving the PS3 a disc?
Further, if you argue that removing the disc is a nuisance when you want to use a blu-ray or other type of disc, here's something to consider. You can:
A) Not mod your console. Swap discs for every different game and every other disc type.
B) Mod your console. Swap discs for everything but games.
So whatsa problem?
