[off topic] Vista instal >7.1 Gb

Which distro installs all programs sources by default?

Gentoo does, and then compiles them

just a comparison, how much space does mac os x take?

Code for RISC processors is inherently more "loose" and of a lower density, so it is not a good comparison. The Mac version of most software is often much larger than the PC version. But I wouldn't doubt it if most of the space was filled by all the graphics and icons.

Aww, it's nice to see a windows installation that is actually 14 times greater than the hard drive on my old computer.
