Mac OS X is obsolete
Monday, November 21st, 2011„About eight month ago, when I cought myself fighting yet another battle with suspend/resume on my Linux-running laptop, I got so furious that I went to the nearest Apple store and bought a MacBook. After 12 years of almost exclusive use of free software, I switched to Mac OS X“
Ivan Kritic
After people at Rockiger read this cite, the decided to bring up a notebook that comes with Ubuntu preinstalled.
Their SatchBook is based on components that work with Ubuntu out of the box. If you are used to Mac OS X you can install Étoilé and reuse most free Mac Apps.
