Windows still relevant? Of course it is. Earlier this week I said that even if Windows 8 is a total failure it would still sell hundreds of millions of units (which means expectations on Microsoft are still to sell many hundreds of millions of units if this is a success). That's a long way from not being relevant.
That said, when I visit a place that has concentrated tech passionates together, like at the LIFT conference in Europe, the Marker.com in Israel, or a hackathon anywhere in the world, you generally see a lot more Macs than Windows.
So, it depends what we say when we say "not relevant."
Look at this node.js hackathon, for instance. Windows was only seen on one laptop: https://plus.google.com/111091089527727420853/posts/JeCfRq4d4b1
These are programmers. So, for this group, Windows is largely not relevant.
These folks are the ones who build the future (node.js is being used underneath many of your favorite web apps). So, is Windows relevant for the development of the future of the web? Not really. Is it relevant as a platform for delivery of those apps? Not really either, since those apps run just fine on everything from an Android phone to a Windows desktop.
Talking about relevance gets everyone's emotions rolling. No one wants to be seen as an idiot, so when someone points out that another platform is more relevant it gets everyone's tail feathers all bunched up. Hey, you start saying the Nikon is better than that Canon I just bought I'll do the same, right? Even though the argument really doesn't matter to what makes a great photograph (at one of our photowalks the winner used a cell phone, which schooled us all that it doesn't matter the equipment you use, it matters how you use it).
The same arguments come when you get car enthusiasts together. I've hung out with the auto press more than once and they look down their noses at my Toyota Prius. They'd rather be driving some exotic car, which makes sense.
Same with +Gary Vaynerchuk
and the band of wine enthusiasts. I've had wine with Gary and he never reaches for a bottle of Gallo when he has a choice. Why? Even though that's probably what most of us drink at dinner it's not the best if you really care about wine.
So, to wrap it up. Windows IS relevant. It will continue selling hundreds of millions of units, even if it's a "failure." Think about that one for a while.
We'll talk more about this on the Gillmor Gang today at 1 p.m.
