One of the cooler things about the Playstation 3 is that you can install Linux on it, fairly easily I might add.
Recently Softpedia posted an installation guide for Ubuntu Feisty Fawn (7.04) on the Playstation 3. So if you want to maybe play some old school games with emulators or you want to do some other type of cool guy linux stuff, well… you can.
The install process isn’t really that long and the great news is that you can keep the standard PS3 OS installed so you can still do all the great things that the PS3 can do.
One more thing I’d like to mention about it, Ubuntu CAN read the Blu-ray disks however you cannot play Blu-ray movies through Ubuntu (darn DRM).
