Lennart has done some good things in the past
In my experience I have had less crashes in the past 15 years with FreeBSD than I have with Linux. I have had crashes with both. I haven't had significantly more blue screens with Windows either, and the ones I have had with windows have been caused by broken hardware or drivers.
Buy decent hardware with proper driver support and most current operating systems are stable. Problem is most people buy bottom dollar hardware.
And power users complained that Apple stuff doesn't meet their needs - yes, that's true. But Apple doesn't cater to the power user niche - they cater to the common user whose needs are fairly simple.
This often comes up, but many of the power users I know (engineers, including network engineers, etc.) use Macs.
This statement is a fallacy propagated by those who haven't spent any significant time with OS X I suspect. OS X looks shiny on the surface, but is extremely powerful underneath if you care to spend a few days exploring it. It marries unix with a friendly UI and some pretty awesome, easy to use automation capabilities (Automator, Applescript). Yes, other platforms have automation tools as well, but they're nowhere near as quick and easy to make use of.
