Re: How about an octal-core ARM based laptop/netbook?
Looking at the power efficiency of ARM vs x86, why oh why don't we have any decent ARM based Netbooks?
I would be interested in ditching Intel too, but I suspect that a more efficient CPU isn't going to make a huge difference in a Netbook, Notebook, Laptop etc, until someone fixes display technology so a backlight is only required in the dark EBook style. Currently LCD based displays try to deal with bright conditions by out-brighting them thus sucking power to the backlight and they always lose when they fight the sun.
It's different for phones because they keep their backlight off and we put it on to view stuff briefly. On a productive computer display, it remains permanently on for hours.
I do have an Intel Celery based Chromebook with a HDMI screen, runs Ubuntu with KDE nicely too, for about 6.5 hours.
