imagine you are like me, who doesn't need windows anymore (i totally deleted it), and then you notice you have a full ubuntu, on a super-thin, passive coled, laptop, with very long battery-times, with very high screen resolutions, etc..... and this laptop is even not expensive... and works on ARM. For example it could also look like the Lenovo Yoga 2, just even thinner, so that it is more like a tablet when folded in tablet-mode. Ubuntu touch comes out in 2-3 weeks, yes it will be not really ready for productive work, but in a few years, i'm pretty sure, it will have all the major software ported on it, that people need for doing productive work (like blender, gimp, libre office,.., mathematica). I also can imagine, that after android for tablet came out, also a android which fits laptops could also appear, after arm-laptops become more popular. Imagine already now, more than double as many smartphones are sold than computers (Last year 700 million smarphones, and this year will be probably around 1 billion smartphones shipped (And I guess tablets where not counted as smartphones)). Imagine in a few years, x86 devices will be just 20% of the arm devices shipped. This will perhpas boost the performance and the progress of arm even more. x86 will not die out, that easily, since many companies are on windows, but the I guess that in the last years, people started to depend less on commercial closed source software running on windows. Enough tasks can be also done in the webbrowser. I didn't use windows-media-player since years, I dont use skype, I have the google hangouts, And now Valve having the target to turn linux into a gaming-platform, this will help too. I guess microsoft will never again sell windows licenses for hundrets of euros to privat persons (like it happened with windows 7), or they risk to happend the same troubles like nokia. Years ago I was programming on windows with visual studio, now QT Creator on Linux, with gcc and clang. I think, the success of ARM just started, and it still has a big future, not only in smartphones.. but also in laptops. And haiku risks to be out of the game.
