> With a Snapdragon inside your PC, you'll no longer need Wi-Fi to fetch your latest e-mail and catch up on Twitter. Instead, you'll be able to get online wherever there's cellular connectivity. I'm not buying the optimism, especially not in the US. The cellular data is still horribly limited. In Canada it is even worse. The "unlimited" plan is surging back, but it has automatic throttling at varying points. Oh and s…

What is stopping manufacturers from adding a cell radio to existing PCs?

I think you missed that news : https://www.engadget.com/2017/05/12/windows-10-will-seamless...

This is basically an emulator though; it will be quite slow.

Emulation is slower but most people will be using browser/office/vscode etc so its just for those extra few apps that might stop you buying the product if emulation didn't exist.

I'm really excited about ARM laptops, but only if:

* They have laptop-class performance, not tablet class performance * They can have more than 4GB of RAM * You can put reasonable sized standard SATA SSDs in them, or user-replaceable M.2 drives. * You can easily wipe Windows off them and put Linux on it.

Nvidia makes an architecture (Denver [1]) that is made by former Transmeta people and is in many ways a direct successor to this chip. In its current forms, Denver is implemented to execute ARMv8 instructions, but it could in theory execute x86 just the same. Now it's performing its internal exotic VLIW instructions by performing ARM "hardware emulation", but it could do x86 "hardware emulation" just the same. Qualco…

Do you have any links offhand about the internal arch? Curious about it being VLIW and couldn't dig up anything on a quick trawl. Good to hear that idea's still kicking around though. Diversity in CPU design is a good thing!

Yeah, it's still a 7-wide VLIW like the Efficeon but it also has a unit to run native arm code in hardware emulation at a lower IPC for code that hasn't been translated. The idea is to run code that's only used once in hardware emulation but to recompile all the hot code to native VLIW execution.

I look forward to learning more about this product. I love that we're moving non-x86 into mainstream consumer products like this (and not limited to low-end chromebooks, e.g.). ARM SoCs lack the backward compatible x86 BIOS-style bootstrap. This is great because it's kinda crazy to think about booting into stuff like MBR, real mode, etc in 2017. But this is bad because without good standards it's really tricky to hav…

This is lunacy. It will break compatibility with nearly all software out there. From games to productivity apps. Like the stuff I actually use a PC for.

> the new operating system will include x86 emulation, giving it the ability to run 32-bit Windows desktop applications unmodified.

If you are part of the cult-like group that dreams of a future Surface Phone, which includes myself, this is an interesting milestone. If such a device has been in the works in the past, Intel's cancellation of Morganfield (Broxton SoC for phones) was a huge set-back.

Microsoft pursuing x86 emulation on ARM, while certainly of interest to low-cost traditional form-factors such as laptops and tablets, is also interesting because it reinvigorates the idea of a Surface Phone. Of course, the reality remains to be seen.

For those unfamiliar, the concept that many of us imagine for a Surface Phone includes an evolution of today's Windows 10 Mobile Continuum feature that, as with Ubuntu Phones and some fringe Android devices, allows a phone to act as a full computer when docked to a keyboard, mouse, and display. While Continuum exists today on devices such as the Lumia 950 and HP Elite x3, it is limited to Windows' "Universal" applications, and does not work with x86 or even older Windows Phone applications. Still, the appeal of a single-device lifestyle is considerable and many people would love to simplify the technology in their life to a phone that is also their desktop/mobile computer. Many of the youngest generation already do this by simply conceding (willingly or unknowingly) they will never enjoy the advantages of computing with large monitors, keyboards, and mice.

In order for a single device to successfully fulfill these multiple roles, it needs to be able to run real applications and not just in a "enlarged phone OS" fashion seen on devices such as the iPad Pro.

If a Surface Phone were to materialize, I would expect Windows 10 Mobile and Windows 10 to become more converged than they are today. When using Continuum on a Lumia 950, Windows 10 Mobile is doing a respectable job of impersonating a Windows 10 desktop; but it's a veneer. For a Surface Phone to be a viable computer, I think it would start with Windows 10 (full version for ARM) and adapt downward to the phone form-factor, rather than today's opposite of a phone-tailored operating system adapting upward. Yes, W10 and W10M are very similar today, but a SP device would, I feel, push them closer together.

Of course, there is no genuine credible news on such as device, and Microsoft has dodged questions, even downplaying the likelihood of such a device. There seems to be a widespread opinion that one should not even try to build momentum in today's phone market, which I feel is shockingly myopic and pessimistic. Of course it's not a simple matter to establish a foothold in mobile, but previous efforts, while half-hearted at times were nevertheless making (slow) progress until Microsoft pulled the rug out from beneath Windows Phone 8. The biggest challenge to a Surface Phone would be bigger than technology: it would be a test of Microsoft's commitment to the idea.

a) only 32bit b) At what speed though? x86 emulation isn't trivial, and arm seems to be sufficiently different in architecture to incur a large translation overhead.

doesn't UEFI resolve all that?
