>What are those reasons apart from having a "better" ui? (Which is highly subjective and if you use a tiling wm Linux is probably the better choice).

- More commercial software available (photoshop, etc).

- OS X is required if you need to run xcode

- Easier to upgrade to the next version of the OS, without having to do a full reinstall

- Better binary compatibility. (Pretty minor issue).

You need to fully reinstall your Linux install every upgrade?

That might be a symptom of Ubuntu usage, but many other distros handle upgrades gracefully. Arch is an example of this.

Perhaps it depends on the distro. You certainly have to reinstall to upgrade to a new version of CentOS (which is what I use on all my servers).
