ARM Based PC's that run x86 code released

I'm sure there will be an ARM mac at some point

The Asus laptop boasts 22 hours of battery life or 30 days of standby, along with LTE that can run at gigabit speeds. HP's tablet offers a 12.3 inch, 1920×1280 screen, 20 hours of battery life or 29 days of standby, and a removable keyboard-cover and stylus. Both systems use the Snapdragon 835 processor and X16 LTE modem, with HP offering up to 8GB RAM and 256GB storage to go with it.

The emulator runs in a just-in-time basis, converting blocks of x86 code to equivalent blocks of ARM code. This conversion is cached both in memory (so each given part of a program only has to be translated once per run) and on disk (so subsequent uses of the program should be faster, as they can skip the translation). Moreover, system libraries—the various DLLs that applications load to make use of operating system features—are all native ARM code, including the libraries loaded by x86 programs. Calling them "Compiled Hybrid Portable Executables" (or "chippie" for short), these libraries are ARM native code, compiled in such a way as to let them respond to x86 function calls.

While processor-intensive applications are liable to suffer a significant performance hit from this emulation—Photoshop will work in the emulator, but it won't be very fast—applications that spend a substantial amount of time waiting around for the user—such as Word—should perform with adequate performance. As one might expect, this emulation isn't available in the kernel, so x86 device drivers won't work on these systems. It's also exclusively 32-bit; software that's available only in a 64-bit x86 version won't be compatible.

So MS Windows code is running ARM. I'm pretty sure that Linux has been running on ARM for a good long time. Although, I guess since it was likely ported to run natively on ARM it wasn't strictly x86 code.

Yeah, it's emulating x86 code - in windows.

Why does that not send shivers of delicious anticipation running down my spine?

Apple is already running ARM Macs.

If it meant adding a touchscreen, it'd be a good balance for general use cases.

The Pros are going to have to stick to Intel for awhile yet.
