Sometimes it seems…

…you should think twice before switching to Mac OS X.

Some guy has said on digg.com:

As a recent OSX to Ubuntu switcher I can safely say that OSX has nothing on the speed and ease of use of Gnome + XGL on Linux. In case you´re wondering.. yes I´m talking about a Finder-less, multiple-desktop aware OS out-of-the-box.

OSX was a joy for the first few years, but looking back it´s an old russian tank where performance in concerned. Try this XGL stuff, it´s l i q u i d.

I´ve never seen fonts so clean or lines so smooth.

Still… I think a Mac is not the OS itself that makes it unique. The hardware is a thing to take into account also. After all, nowadays you can run either Mac OS X, Linux or plain Windows on a Macintosh freely.
