Agree. I'm on OSX. I've used many different Linux distros but they don't have that 'just working' touch yet. I must admit, Ubuntu is pretty damn good though. It sucks trying to make stuff work that just should on Linux. I'm sure that one day though things will change.

It also needs better cohesion between design and code...

If by "cohesion between design and code" you mean "more attention to the design and usability aspects" then I agree.

What Linux still lacks in my opinion is a coherent and usable design. KDE4 and Unity/Gnome3 are trying, but I think they are not there yet.
