If that runs great on phones, and has virtualization support for e.g. running ARM Linux guests, I would change both my Android phone and my Ubuntu laptop for one phone (e.g. Snapdragon 835 or better + 8-12GB RAM + 256GB flash + USB 3.0 OTG), using a dummy screen + keyboard as laptop replacement.

I am not sure there is a huge gap from dummy screen + keyboard + battery to laptop and your not going to be able to power a laptop screen from a cellphone battery.

Does the x86/x64 cpu emulation work for JIT code or other self-modifying code? (Copy protected games, for example?) In the linked presentation they just briefly mention doing a load time(?) transpile of x86 to arm64 and caching the result on disk. What about exe packers that map memory rw then rx after unpacking, such as UPX?

They say that it's a dynamic translation layer, so presumably it doesn't make a distinction about where the code came for (except maybe you'll lose some performance optimization if they are caching translated code)

I hope they drop this on the surface 2. It would save it from being a paper weight.

Was the SurfaceRT an ARM device? I have one collecting dust, would be nice if it got an update

Yes. The RT devices ran ARM, which was one of the reasons for the locked down software policy (nothing else would run anyway).

A qualified guess would be that you can just install it, because the bootloader is Microsoft signed so it would pass the secure boot check.

Edit: Apparently Surface 2 isn't AArch64, so probably not.

I would use the "dummy screen + keyboard" only when plugged, obviously.

Maybe you are describing the rumored Surface Phone?

For any Microsoft insiders with knowledge about this, a few questions:

1. In the talk they claim that they get "near native" speed from the translation. Can we have some real number of what can be expected? What about warm up time?

2. Is the x86 translation layer only available in user space, or can x86 drivers be loaded for hardware that doesn't have arm drivers yet (or the manufacturer doesn't care about making them)

3. Are there any plans in the future for supporting x64 code as well in the translation layer?

Edit: One more:

4. Are there any plans on supporting Arm v7 in the future, e.g. with Surface/Surface 2 support?

Great potential for a Win10 phablet I can develop on that also lets me make phonecalls. Not for big projects, but an anywhere device. Does Win10 support non VoIP calls?

I think it does since MS did a big overhall on their windows architecture, phone, xbox, and desktop all run the same base services just with different GUI's. Technically an XBOX could make phone calls but has no GUI or hardware for it.
