I would like to see A HDD available some time soon after or on launch, but, I dont see much use for it, at least not yet.
Consoles still lag far behind PCs when it comes to having downloadable content ready available on the web. If PS3 did include A HDD I doubt you would find any 3rd party sites to download extra cars/tracks. Polyphony Digital may release a few tracks to download and a few cars but I dont think it will be anything like the PC world which has thousands of 3rd party guys making tracks planes cars etc.
So what would you need a HDD for? MMORPGS? I think thats about it.
Now that I think about it, there really is no need for a HDD for consoles except for internet use, and if you have a PC then why use your console? If I could save my game files from my PC games to a floppy disk I wouldnt need a HDD even for PC games. HDD is overrated and rarely used/needed. I\'m sure if XBOX didnt have it nobody would care that PS3 doesnt have it.
