Imagine a future where Android was the only mobile Linux around (on phones, tablets, netbook, ...). Imagine that it marginalized Apple completely and emerged as the only standard "high end" mobile operating system.

If you are a Linux guy, there is a chance that you wouldn't like this at all. It would be a pyrrhic victory; Linux won, but there is nothing Linux-at-large (desktop, server...) would gain from this, apart from perhaps a few drivers. Unless we start seeing Android seeping to desktop space, so that we could rm -rf everything the Linux userspace community (GNU, X, others) has achieved through these ~20 years and replace it with a Java sandbox written by a company Google bought.
