there are so many distro's of linux i dont know what to recommend, if you ubuntu is probably the most supported version out there right now, and with linux you can have linux and windows installed on the same drive without reformatting (although it resizes your partition). Gourav i doubt you'd have much fun using linux because everything you install has to be done with .tar commands through terminal so like have fun doing that kind of shit, i just uninstalled my linux distro last night because i never use it (PclinuxOS 2007)
