Ubuntu is a free and open source Linux distribution. It has been awarded as being the most user friendly Linux distribution, and it arguably has the most functionality and beauty of all desktop Linux distros. What would be the economic and social benefits to the individual and society? Would there be any disadvantages to its adoption?

I don't care for the default interface on the PS3, the 360's is much better in my opinion. I am not familiar with Linux at all. I know what it is but have never used it. I am curious to know what advantages or even disadvantages come with installing one of these OS's on my PS3 (60GB)? Does it effect the functionality of the system? Do I lose any features? Is internet browsing better? How much memory does it eat? etc. etc. Please explain in detail. Thank You.
