⟩ How to make Eee PC running Linux look like Mac OS X?
The Xandros system does not allow this extent of modification. You would need to install another Linux distribution on the Eee. Two distros that have a GUI similar to that of Mac OS X are gOS and Dreamlinux. gOS is designed for low-powered devices like the Eee, so it should be a good fit. Dreamlinux is not tailored for the Eee, but has low system requirement.
