Not Linux? No point, other UNIXes

Is there anyone seriously suggesting these days that a non-Open Source Linux is worth having? I ask this as someone who has tracked the whole 'Open Systems' (remember that tag line?) debate since the late 1980s, UNIX International, Open Software Foundation and all the rest... There is plainly proprietary UNIX out there that is excellent/has its good points/the supplier made me buy it because he has all those pics of the trip to the dodgy club in Tijuana, etc. But beyond legacy, there just can't be any non-Linux fresh projects starting. And if there are, you're mad, so stop. Please.

But then I still dip into this very funny book now and again, so what do I know...
