<blockquote>Right now we don't yet have enough pieces to directly attack desktop so Linux developers have few years of opportunity - and it's not at all clear that we can offer something better then Windows and MacOS, but we are thinking about it, believe me.</blockquote>
Who is 'we' here? I was following the discussion OK until this point.
All I will add to the discussion is that it is true that there is a lot of obscure software not available for Linux (e.g. building supplies companies calculators for number of fixings required per foot). This is annoying, but in a fairly minor way.
But the preditions of the death of Desktop Linux are overstated IMHO. I can't see any prospect of ever switching to anything else, and I expect I'm not the only one. Freedom is much more important to me than random bits of (mostly unimportant) software not available on my platform. I don't see that changing. And I'm very happy with the integration job my distro does. The userbase could shrink enormously and I'd still get the main benefits I came for. And actually I don't see a shrinking userbase at all, although that may be the circles I move in. Certainly usage is growing fast amongst developers at the large company I work for.
