Google Nexus 7 does run on Linux.

Can we stop calling Android Linux just because it shares the Linux kernel? Obviously the author was referring to a GNU/Linux distro.

Well, the kernel does device, process and memory management and that is a likely culprit when looking into power usage.

The issue has to be engineering. Is it a case of too much distance between the HW and SW people?

> The issue has to be engineering. Did... did you just invent the technology version of Fr Jack's "That would be an ecumenical matter."

Reminds me also of Jim Hacker and Sir Humphrey Appleby in Yes Minister, who dodge constituents' questions with "That would be an administrative matter, you must ask Sir Humphrey" and "That would be a policy matter, you must ask the minister", respectively, until one woman complains that they always shift the blame to the other, and Sir Humphrey makes a long, obfuscating speech about the administration of policy vs the policy of administration, bamboozling her.

For this purpose, "Linux" is still too general even when restricting ourself to traditional GNU/Linux distributions. The answer may depend on which exact services a specific distribution runs by default, as well as kernel configuration.

I'd be interested to see the answer for an out of the box Ubuntu distribution (latest stable version), as well as the answer for Red Hat Enterprise Linux, to cover the "leading brands" for the consumer and business markets.

Because re-writing for a new platform isn't trivial. Because the customers want it. They're intelligent enough to know that a tablet isn't going to be as productive as a desktop/laptop. But they still want it.

Customers generally do not want to run Windows apps on their tablet. If they did then Surface Pro would be the number one seller.

Existing windows applications are by definition best suited to desktops and laptops.

Our's would be such an application but even as it is there are certain aspects of its typical daily use that might/would be best served by a tablet.

At those times it would be nice for a user to be able to switch from one device to the other and then back again.

In fact, requests like this are becoming more frequent.

A quick Google search shows many Windows laptops with equivalent or better battery life. Is your question why don't all Windows laptops have equal battery life?

> A quick Google search shows many Windows laptops with equivalent or better battery life. I don't want to state the obvious, but different laptops have different capacity batteries. Atwood was comparing the 11" MBA to the Surface Pro 2 as they have similar battery capacities (SP2: 42 Wh, MBA: 38 Wh), and - as Maakuth notes -- are both made by companies in control of both software and hardware. The fact that you can…

A 100% true test is when you have the same hardware. Running windows on MBA is defect because Apple writes iOS for their hardware. So if we have a magical power to run iOS on another hardware and run Windows on that same hardware, then the test is fair. But that doesn't need to as windows-based tablets hardware are not always as polish as apple's.

Mac apps can't run on iOS because of the architecture difference. It's the same reason Windows apps can't run on Surface RT.

They could. Apple run PowerPC apps on Intel processors. The real answer is that they don't want them to.

Apple ran PowerPC apps on Intel processors. The real answer is that they don't want them to.

Rosetta is neither included nor supported in Mac OS X v10.7 "Lion" or later. Therefore, with Lion and later releases, the current Macintosh platform does not support PowerPC applications.

Microsoft turned Windows 95 into a full-fledged multi-user operating system. Segmented user space? Unix had done that for years. All users where admin and it was horrible, but lot's of apps ran on it, so people bought it and used it. Then they merged Win95 into WinNT and gave us Windows 2000. Now they are turning a full-fledged multi-user OS into a tablet OS. Let's make this tank into a bicycle. History tells us ther…

I'm curious to know what they took from W95 to give W2K. I've used NT3.5 and up and I didn't notice any w95 influence, unless you mean start button and desktop.

While the core subject seems fair enough, I'd expect Atwood not to be so utterly stupid by trying to swap out Apple OS X running on one of a highly restricted variety of Apple Mac hardware with a generic Windows install and expect the result to be competitive. That's boxes-with-arrows mentality at its worst right there.

In any 5 year period, Apple has a tiny list of exact hardware configurations OS X is designed to run on. It's so small, they even use the OS X software update mechanism to push BIOS updates! They have so much room to do better than Microsoft here it's barely even funny. This isn't an excuse for Microsoft's poor performance, but if you try to gloss over the fact as Atwood does here, then you're omitting the full truth.

Later in the article Atwood does compare it with a non-generic Windows install:

The benchmark which is missing to make this article more relevant, though, is to measure and compare a hackintosh (i.e. non-apple PC + Mac OS X) battery performance.

That's a very strong assumption... The only reason I have an Ipad rather than a Surface Pro, is because it didn't exists when bought my Ipad, sure thing that will be my future tablet in my next cycle, and I feel I am not alone. I think surface is not doing it better because it came into the game too late but it is a nice replacement for my heavy laptop and my Netflix viewer (namely Ipad)
