    That is, when there are good enough GPU (and everything else as well) FOSS drivers for at least one of those SoCs?
    You could build your own RPi powered laptop with fullhd graphics?

      I don't know of any plans to, and that's likely because consumer software is still largely single-threaded and responds to fast individual cores, which is exactly what ARM sucks at compared to existing desktop hardware.

      It's useful in servers because things like apache run very well on it.

        You can do that now. I know some folks who run fedora on (arm) Chromebooks.

          Many parts of consumer software could be parallelized even on x86 / ARM. Of course you don't need to accelerate stuff that does already run sequentially. Quite many apps actually run just fine on a single 1.5 GHz arm cortex core. Many apps could benefit a lot from ARM SoC with GPU and 4-8 cores. Too bad this is not the case.

            But not with open source drivers.

              Well, there is freedreno which (IMHO) runs pretty well on any adreno 3xx generation device (ie. any recent snapdragon).. and you don't even need a bleeding-edge mesa (10.2 will do). The rest of the kernel situation for snapdragon has lagged behind compared to some of the other SoC's, but has made a lot of progress in the last couple months. I can run upstream kernel plus ~20-30 patches on my ifc6410, for example.

              The upstream kernel situation seems to be pretty good on freescale imx6 and etnaviv is looking pretty good too.. still missing upstream gpu driver and DDX, but work is underway on both, so I expect good things in the relatively near future. Hopefully once the dust settles on this we can get the etnaviv gallium driver into upstream mesa, which will make life easier for distro's.

              Anholt is making fast progress on vc4.. so for r-pi I guess things will be usable in another month or two.

              And of course, with the new tegra k1, nouveau is already up and running, and the nvidia arm crew has been doing a good job with getting upstream kernel situation sorted.

              Ofc, as is the case w/ FOSS graphics, there is always more to do.. but the situation for FOSS arm graphics is looking pretty good. Much less dire than it was a couple years ago.

              On phones/tablets, compared to dev boards, the situation is a bit worse. But that is mostly because android lags on kernel version. Plus bonkers vendor kernel branches. Eventually as android rebases and starts to inherit all of the recent upstream kernel work on arm, this will improve.

                Yeah. Sadly, that's true
                IIRC, they're all exynos (but not mali).

                  There's a Chromebook with a TK1 now.

                    You're right! Thanks for the correction.
                    It looks like they're all Acer and 32bit. I hope they bring out Denver in various form factors soon. I'd love to play around with the new isa, not to mention the dynamic, native code optimization tech they licensed from transmeta. Those old transmeta chips were long gone before I got involved with programming: (

                      Also: did the Lima project move or why were neither the website (limadriver.org) nor the gitorious repo updated after mid-2013?
                      Try asking at their irc. #lima on Freenode.
