Linux has better hardware support than OS X
Interestingly, I run Ubuntu on a MacBook and a MacBook Air.  As they are a "fixed" target, I figured that at least one developer would have made sure that they "just worked".  And, indeed, they did.The installation tutorial was comprehensive, the out of the box experience was great, and upgrades have gone smoothly.The only thing to note was that I was able to manually update the WiFi drivers for (supposedly) better performance if I wanted.  Power consumption seems marginally higher, but I don't run the same profile of programs in OSX.Having a fixed target is really good for Linux to show how it can shine - and I hope that Dell and Ubuntu continue to make perfectly matched hardware and software.
