You can always install Linux or some other OS (other than OS X) on it. I'm sure it would run quite well.
I believe ShadowAce made a comment once regarding Linux and Windows Service Packs...
While no one disputes that Linux is a good OS, there is also no doubt that, it’s not ready for prime-time when it comes to the PC market, as demonstrated by the rejection of the OS by 99% of consumers for more than 20 years. But, keep trying; Linux might become the OS of choice after Windows and/or Microsoft drop dead, some 200 million years in the future.
