When you take into account servers and Android OS, I'd say Linux has been fairly successful. There are large numbers of people using it without even realizing it (or caring). Bitcoin can achieve a similar success.
Also don't forget OSX and iOS are both based on the Linux kernel.
It's true that usability and accessibility must be improved in order to accelerate adoption of Bitcoin, but even if those improvements are slow to come, I don't think Bitcoin will die right away. It's already carved out a good niche and developed a devoted following. I don't think anyone's crystal ball can predict what we'll be doing with bitcoins 2, 5 or 20 years from now.
