The removable Harddrive. Yeah, it\'s not out yet.. but once it is, it\'ll be an indespencible tool. See, I like gaming.. and I\'m an active member of the abandonware/Rom scene so my HD\'s are packed with old games. The only problem is, I don\'t have a CD burner and if there\'s a crash or a virus.. I\'m phucked. The PS2 will hopefully provide a much more stable enviroment to hold my games on until I can upgrade my PC. I just hope it\'s got a flexable user interface... say like a basic Linux OS that\'s capable of running a modified WINE.
If nothing else, I\'m sure someone will come up with a way to use the USB ports to transfer data over to the PC for whatever reason and I\'ll just use that transfer the games I want to play at any given time. The fact that it\'s removable means I can have several 40 gig HD\'s filled up and never really run out of space.
The big reason is the static hardware though. You can say goodbye to many runtime errors and incompatabilities since emulation drivers don\'t have to be written for a million and one different combinations of hardware. I just hope slowdown proggys like Turbo or CPUKiller don\'t fry out the EE. If enough people think the way I do, then hopefully someone will write an EE specific slowdown util.
