At a mini-conference I attended recently, I noticed that practically every speaker with a Mac was having a hard time getting their computer to play nice with the projector. The PC users were not having this problem.
I'm still quite happily using both, but OS X has been spiraling downward and Windows has been spiraling upward for a while now. I wonder if I might find myself thinking back on that conference as the moment when I realized that one overtook the other.
It's pleasing (but also frustrating) to see that there is still some back and forth between different OSs.
Dual monitor is something that really really should be a solved problem.
Many developers use more than one monitor. Many professional (with big budgets) customers use more than one monitor. Multiple monitors make great sense for many people and many user interfaces.
And yet sometimes it's a hideous kludge. randr, xrandr, etc are for most people impenetrable gobbledygook. You've seen people struggling to get modern computers working with projectors. People on HN often mention the frustrations of weird behaviour with multiple monitors.
