It's still early days, but this has the potential to put more fuel on the Apple rumour mill fire than anything else in recent times. A BA thesis by Dutch student Tristan Schaap details how, during his internship at Apple's Platform Technologies Group, he ported Darwin to a certain ARMv5 developer board. A few blog articles later, and the headline has already turned into 'Mac OS X ported to ARM'. So, what have I been running on my iPhone and iPad all these years?

Intel is far from stagnant, though, and ARM is many years behind in performance. Switching to ARM right now would be like switching to Atom, i.e. relaunching the Air as a netbook. It does not quite make sense.
Here are some recent benchmarks on Linux, with Tegra 2 being not quite half as fast as a Core Duo (from 2006):

Great resource. I didn't mean to imply that Intel was stagnant, just that Apple, and other vendors, are obviously heavily invested in ARM on mobile, and that Apple in particular knows what it's like to end up with all its eggs in the wrong basket. Right now there's a clear division with ARM in the battery-efficiency column and Intel in the performance column, but that's likely to shift over time.
And the shift could certainly be that Intel makes big inroads into efficiency and erases ARM's advantage there.

But you're comparing this generation of ARMv7 to Intel but skip what ARMv8 bring to the table for both 32bit and 64bit computing specifically when it comes to performance. Right now it would be suicide for them to adopt ARM but I could see in the future ARMv8 laptops, desktops, workstations etc. centred around very efficient multicore CPU's with software taking advantage through a combination of Grand Central, GPU offloading for things like video encoding/decoding. In 5 years time a lot can happen.
Edit: And the benchmarks btw say more about how optimised the software is rather than whether or not ARM lacks raw performance when all things remain constant.

"In NixOS, the entire operating system - the kernel, applications, system packages, configuration files, and so on - is built by the Nix package manager from a description in a purely functional build language. The fact that it's purely functional essentially means that building a new configuration cannot overwrite previous configurations. Most of the other features follow from this." Interesting approach. A Linux distribution, sure, but with some very refreshing ideas about system configuration.

Google added, among other features, C/C++ support to its new version of AIDE. From Android-IDE, "Now you can write parts of your app or your whole app in C/C++ on your device. AIDE supports the Standard Android NDK toolchain (GCC 4.6 + Bionic, STL, ...). No changes are necessary if you want to build an app developed on a PC with Eclipse. C/C++ development is fully integrated: Build errors appear in the error list and files can easily be navigated to with Go to file. The editor supports C/C++ syntax highlighting."

Ars nails it: "The answer is that Google did announce what amounts to a fairly substantial Android update yesterday. They simply did it without adding to the update fragmentation problems that continue to plague the platform. By focusing on these changes and not the apparently-waiting-in-the-wings update to the core software, Google is showing us one of the ways in which it's trying to fix the update problem."

"It is good for programmers to understand what goes on inside a processor. The CPU is at the heart of our career. What goes on inside the CPU? How long does it take for one instruction to run? What does it mean when a new CPU has a 12-stage pipeline, or 18-stage pipeline, or even a 'deep' 31-stage pipeline? Programs generally treat the CPU as a black box. Instructions go into the box in order, instructions come out of the box in order, and some processing magic happens inside. As a programmer, it is useful to learn what happens inside the box. This is especially true if you will be working on tasks like program optimization. If you don't know what is going on inside the CPU, how can you optimize for it? This article is about what goes on inside the x86 processor's deep pipeline."

"It was the only moment I heard regret slip into Otellini's voice during the several hours of conversations I had with him. 'The lesson I took away from that was, while we like to speak with data around here, so many times in my career I've ended up making decisions with my gut, and I should have followed my gut,' he said. 'My gut told me to say yes.'" The world would've been a much different place - Apple would have been less dependant on Samsung for its chips, which probably would've meant less money for Samsung to develop its Galaxy business.

Glass is getting some love at Google I/O as well. New applications have been released - Facebook, Twitter, Evernote, Elle, Tumblr, and CNN. Perhaps more interesting: the newly announced Google Glass Developer Kit will allow offline applications and direct hardware access - great for hacking and expanding Glass' potential. This kit will really allow hackers to put Glass through its paces.

"But Beck and Merrill decided that simply banning toxic players wasn't an acceptable solution for their game. Riot Games began experimenting with more constructive modes of player management through a formal player behavior initiative that actually conducts controlled experiments on its player base to see what helps reduce bad behavior. The results of that initiative have been shared at a lecture at the Massachusetts Institute of Technology and on panels at the Penny Arcade Expo East and the Game Developers Conference." Absolutely fascinating stuff. I'm a League of Legends player, and to be honest, the community isn't nearly as bad as some make it out to be. I'm happy Riot games has the guts to employ science to address the issue.

"Android and iOS, the number one and number two ranked smartphone operating systems worldwide, combined for 92.3% of all smartphone shipments during the first quarter of 2013 as Windows Phone crept past BlackBerry for 3rd place. According to the International Data Corporation Worldwide Quarterly Mobile Phone Tracker, Android smartphone vendors and Apple shipped a total of 199.5 million units worldwide during 1Q13, up 59.1% from the 125.4 million units shipped during 1Q12." Windows Phone doubles from a few to twice few, iOS loser market share as its growth is slower than that of the overall market. BlackBerry continues slide into irrelevance.

"During its Keynote today, Google announced new features coming to its flagship search function - you know, that thing we all started using Google for. VP Amit Singhal spent some time discussing what Google's search functionality will eventually morph into. Google's strategy is summarized by three words: answer, converse, and anticipate. Singhal explained that many of the pieces of these upcoming changes can already be seen in products that Google has recently introduced - namely, Google Knowledge Graph and Google Now, with perhaps a splash of Google Glass, too." I hold on to my hat every time Google changes Search. It's such a vital product in my daily life.More News »

Apple's become pretty cozy with Intel in the past few years, but I'm sure that you're right. Maybe Apple will always use Intel chips for it's higher-end computers, but I'm sure how they remember how uncomfortable it was to get chained to the comparatively-stagnant PPC platform.
