These laptops are running with Microsoft's ARM version of Windows 10
On side note I wonder what apps ppl would use on Windows for ARM. Wintel put a great deal of efforts to persuade devs there could be just x86 and win32. It has worked, so hard many Windows programs aren't completely ported even to x86-64. I could imagine ARM version would enjoy real lack of programs and apps. Hey, sounds like WinRT 2.0!

I see that other makes are jumping on the WinArm bandwagon:

"Samsung and Xiaomi are both said to be working on Windows devices that use Qualcomm’s flagship processor."
perhaps Xiaomi will be more open to running linux on their device, with any luck they will be lazy about locking down their boot loaders ;-)

So I wouldn't take it as granted. My impression is that x86 is large, complicated and really suxx when it comes to power management. No matter what Intel did, their x86 ICs failed on low-power markets. Oh, they've also gave up on their SBCs because only craziest of fools would deal with x86 in small embedded designs.

Your Coretex-M0 would end up grossly inefficient in that case because the compute capability compared to the platform power usage would be abysmal... but you're right that for something like IOT or a Nook, ARM is a winner.

Originally posted by SystemCrasher View PostNope. I referred to Cortex-A series, which are more or less meant for "computer-like" devices and could implement PC-like things, be it USB or PCI-E, etc. Tablets, smart phones, embedded computers, low-power laptops, etc are using Cortex A as main CPUs. Some 64-bit things like A5x and somesuch appear to be "good enough" even for general purpose computers.
Nobody uses cortex M0 as main CPU in e.g. tablets. There're fairly decent cortex A things, some could easily score like 4-8 64-bit cores at 2+ GHz or so. Being quite a powerhouse, capable of being more or less generic computer, as long as software part permits. This said, ARM cores are much smaller and aren't as grossly overengineered like Intel, allowing smaller system size, easier implementation and low power consumption. Whatever, Intel thrown great efforts trying to tame x86 power consumption in mobile devices, but it never performed reasonably. If we take certain battery wattage, ARM devices last considerably longer. I've seen some x86 tablets, Android and Windows ones. Their battery lifetime was really bad compared to ARM tablets. To get reasonable lifetime, x86 devices need really HUGE battery. So x86 power efficiency tells for itself.

Yesterday I was able to play around with the NovaGo at some shop. A reboot did not show any kind of entry for uefi; but the manual from ASUS states that it is possible to change uefi settings from Windows settings and to boot from usb devices. I.e., with the proper image it should be possible to boot Linux. Secure boot remains to be an open question though.
