Even if we have a perfect kernel, it won't insulate us from bugs in the software running on top of that kernel, so do we really gain much? I guess for mission critical apps the answer could be yes... But for every-day computing?? On my desktop I have more trouble with Firefox crashing than I do the OS! (Yes I run linux).

My car has daytime running lights and I forgot to turn on my headlights then wondered why I couldn't see very well.

It got darker... As I was driving up a hill I realised I had no idea which way the road was going. Not to worry - I looked over to my 3D sat nav map and saw the road continued straight. Excellent!

What do I drive? You guessed it, an old boxy Volvo!
