HereÃ¢â¬â¢s an interesting compilation of Linux distribution which resemble AppleÃ¢â¬â¢s Mac OS 10. They might not be identical, but you guys who like AppleÃ¢â¬â¢s design might appreciate the fact yu can get something like it, with the nice-on-the-inside GNU/Linux kernel, out-of-the-box. For free.
These are only short descriptions, with screen grabs. You will find a lot more info and full screenshots on the official web pages of each distro.
