I had a brief Twitter conversation with Anand Shimpi of Anandtech about this, and he was as perplexed as I was. Nobody could explain the technical basis for this vast difference in idle power management on the same hardware. None of the PC vendors he spoke to could justify it, or produce a Windows box that managed similar battery life to OS X. And that battery life gap is worse today - even when using Microsoft's own hardware, designed in Microsoft's labs, running Microsoft's latest operating system released this week. Microsoft can no longer hand wave this vast difference away based on vague references to "poorly optimized third party drivers".

The new Surface Pro 2 gets 6.6 hours of web browsing battery life. The MacBook Air 11", which has more or less the same hardware and battery, gets more than 11 hours.

I have a Surface RT - the first generation - and as such, I know why. Windows 8 might have Metro running on top of it hiding a lot of it, but Windows 8.x carries just as much baggage, cruft, and outdated shit with it as previous versions of Windows have. Windows 8/8.1 - and Metro in particular - simply suck. Slow, clunky, jarring, cumbersome, battery-sucking, restricted, and limited, with a crappy selection of rush-job, rarely updated applications. You know how resizing windows on Windows 7 or OS X is all nice and fluid? Why, then, is it a slow and jittery operation that brings Windows 8 Metro to its knees?

It's simple: just like battery life, it's a symptom of Microsoft's Windows team not having the balls to truly go for a clean break, as the Windows Phone team have done. And lo and behold, Windows Phone - even WP8, which runs on the same NT kernel - has none of the slowness and crappiness issues that continue to plague Windows 8 Metro (although WP has its own set of issues unrelated to these).

If you want a smooth, modern laptop today - get a MacBook. If you want a smooth and modern tablet, get the Nexus 7 or an iPad. Microsoft still has nothing to show for itself in these areas.

No jitter on surface pro

I have absolutely no graphics issues on my Surface Pro on any app resizing. I would assume the poor graphics performance is due to the RT and its inadequacies. I have also never experienced any graphics issues on other laptops, BUT I have never tried Win 8 on a non x86 cpu so I am not sure if Thom was specifically speaking to RT and RT hardware.

Re: battery life, I still think it's tough to judge because it's not a 100% fair comparison because Windows has the whole touch screen and higher res display to deal with whereas Apple doesn't (comparing Surface Pro to MBA). Apple has also been making/controlling their own hardware a lot longer.

Despite all this, I still feel that if Apple did have a touch screen and higher res display, I wouldn't be surprised if they managed to have significantly better battery life than the competition.
