I switched to OSX for exactly the reasons the author mentioned. The fact that I have an awesome UI + ability to use the shell all day is a huge win for me.
However, people cannot switch to OSX. The machine that ran Windows XP and Linux WILL NOT run OSX. So, no, you didn't switch to OSX, you purchased new hardware that is strictly controlled (motherboard, video card, etc).
Then, in an incredible blunder, de Icaza said, "Many hackers moved to OSX... working audio, working video drivers, codecs for watching movies..."
Uhhhh, yeah, if Linux gave up on supporting scores of hardware platforms and hundreds or thousands of hardware components, OF COURSE it would have working audio, video drivers, and codecs.
Needless to say, the sound didn't work. And the wireless didn't work. When I clicked "suspend", it said it was out of swap space. When I closed the lid, it crashed.
And since most things are web-based now, a vanilla KDE setup + Icon-Only Task Manager is awesome enough for me.
