You can run some emulators and such, but really there's not much unless you really want a PPC Linux install that can't do 3D rendering
You could also do some serious number crunching on the PS3 hardware, but if that wasn't your express purpose for installing Linux, you probably don't care.
In fact most things on PS3 linux are horrible, because 1) Sony only allows the other os to access a small subset of the hardware, which last a checked excluded the GPU 2) the vast majority of applications are not optimized or designed for the cell processor.
If your think of installing Linux on your PS3, I would advise against it.
Anyway, yes, you can remove Linux from the PS3 and, yes, you DO have to reformat your whole drive to do it. You can, however, back your important stuff (i.e. downloaded games, DLC, save games, pictures, music, etc.) up to an external USB hard drive (or flash drive if it's big enough) and restore it after you're done formatting.
I had the same dilemma. I had installed Linux, used it once and realized later that it would be nice to have that 10GB back.
