Hmm. Here's my read of it: Apple & Google currently own the mobile OS market. Microsoft, after failing to gain market share with Windows Phone, is (as usual) retrenching into their desktop OS and trying to spread it out onto mobile devices (which, I suspect, isn't going to be a winning solution either). So, if you're interested in an alternative mobile OS, what are your choices? You could start from scratch, spending many years and millions of dollars to come up with an alternative. You could go with Firefox OS, but the goals of that OS seem to be far more limited in scope than iOS or Android. You could wait (and wait (and wait)) for Ubuntu Touch to slowly, ever so slowly make its supposedly inevitable way into the commercial market, should that ever happen. Or, you could try Sailfish -- which is ready today and has been designed specifically to rival Android and iOS as a first-class general consumer mobile OS.

Honestly, I can't myself imagine that many folks are all that interested in an alternative to iOS or Android right now. Members of TMO don't seem to have much love for the current mobile OS leaders, but the two titans still seem extremely popular in the general market. But yeah, if there are any such folks out there, investing in Jolla should still be at the top of their list -- I believe it has a much better chance of becoming a viable alternative to the duopoly than anything else available right now...
