x86 was too entrenched; That was why RISC derivatives all failed.

I'm good with Linux as a workstation platform and definitely rooting for it as a server platform, but its nature makes it hard to grow in the personal computing and below segments. Unless someone comes up with the ability like NT4.0 to run on Alphas and x86 at the same time (and on a phone?), the Atom's pretty much in need of blue oceans.

And although Apple loves Intel, I'm pretty sure that they've settled down on ARM and the respective software ecosystems. I think that Tegra's the next logical progression for them- Cortex still needs more solutions with it in before it's that ready for mass deployment. I'd get one of those Archos internet tablets to see how it is in general, though.
