BeOS 5.0 Pro.

Apple was doing rough in the 90's, at some points, and it would have been nice if Be had taken advantage of the situation. Apple had too many different models. Going Unix seemed to be saviour.
Hmmm, set-top boxes, the electronic omen.
edit:
I noticed that Haiku has a Galium bounty posted on it's front page.

Ya, the quality of their "Alphas" have been more than impressive! They got their priorities in order. Rather than focus on eye candy and advancements that would only be useful on a stable OS, they first make sure that the OS is stable and works as it does for the most important things. Everything else can be fleshed out later.

Check my Album, I got a snapshot of Haiku in Virtual box.
