Probably will be interested in what *nix brings to the game. This really ties into ecosystem lock-in. As FOSS users, you really don't *have* lock-in, but you probably have emotional investment in *nix platforms that will drive a certain amount of adoption. I think Ubuntu in particular has made it clear they see the change coming and they want to remain an active player there. Which is *good*.
On the other hand, I don't see the *nix distros actually making any radical change to the traditional division of market share through these changes. The *nix distros will inevitably remain a small niche player and a perpetual thorn in the side and gnawing concern for the incumbents.
Even if they really nail it, they have a logistics problem with getting the word out. If that changed somehow and Ubuntu was able to afford millions or billions of dollars in advertising revenue for main-stream, prime-time advertising like Google, Apple, Microsoft and Intel are investing in - then things could change.
I think I'm an awesome blogger who should have hundreds of thousands of dedicated readers who constantly demand more content from me. I'm *certain* it is that I don't have the same kind of visibility, not a lack of talent or credibility, that prevents me from having the kind of following the A-list, top-tier tech bloggers have. I'm the Ubuntu of technology bloggers, under appreciated except by a minority of readers with exquisitely demanding tastes.
