You need OSX. In a lot of ways it's a shame Apple won't allow it to be used on standard Intel hardware. I could see a lot of people who are tempted by Linux being drawn in by a system that has the stability of Unix, but is more user-friendly than Windows.
Unfortunately for Linux, most of the desktop managers out there fall into one of 3 categories:
- 'My first computer'
- Amiga Workbench circa 1989
- Desperately trying to look like XP
Aside from the installation issues, it's the 3 points above that make Linux so hard for me to like.
