I don't trust product demos, movie trailers nor press releases, so I'll reserve my enthusiasm until someone on the "real world" has had the chance to get their hands on this.

What I know is this: ARM emulation via QEMU on my core i7 was pretty slow last I tried it. Not unusably slow, but still slow. And I have tons of ram and a fat CPU.

These laptops, especially if they are made on the cheap side, won't have tons of RAM and a fat CPU. Unless Microsoft pulled some magic tricks, I don't see this emulation being usable.

But I could be wrong.

"faster than QEMU" isn't a particularly high bar to clear, though. In particular if you're only emulating a single process rather than a full guest OS then you can reduce the overhead quite a bit. Plus if you design something from the start for the single-process emulation case, and only need to worry about one guest and one host architecture, and focus on emulation performance as a key goal, you can likely do better than QEMU without too much trouble.
