blogoculaire asked:

What is the percentage of time you use your iPad(s)/iPhone versus PC/MacBook(s). Can you make it to 100% soon?

I’d say it’s probably 70/30 on iDevices vs. MacBook. Most of the MacBook Air time is work-related. And that figure is so heavily tilted in the iDevices favor because I use the iPhone far more than any other device.

That said, when it comes to “general computing”, I much prefer to use the iPad Air (with the Logitech keyboard) for almost everything. But I suspect a rumored 12” Retina MacBook Air could tilt the numbers back in the MacBook favor, if only temporarily.

Robert McMillan quoting Intel engineer Per Hammarlund:

“We see this as very important, and it’s an area where we have been putting in a lot of of effort, and we’re continuing to put a lot of effort into it,” says Hammarlund. When you consider how most people use mobile phones, sprinting makes a lot of sense. “You appreciate having really snappy responsive system behavior for very short bursts of time. And other than that, you really want the system to consume no power.”

The idea of “burst computing” is definitely interesting with regard to mobile — that is, you want everything to happen really fast for a few minutes while you’re using the device, but then you don’t care what it does when you put it back in your pocket.

On the topic of the PC plummet, here’s Matt Rosoff:

You can hash the numbers any way you like, but the trends are clear. The PC market is getting crushed by tablets. In fact, I think we’ve reached a tipping point that will mean the near-total collapse of the consumer PC market within three years. By mid-2016, consumer PC sales will be less than half of where they are today. Probably way less.

A few years ago, such a claim would have sounded beyond outrageous. It doesn’t anymore. 


Personal computers will be a relatively expensive high-end product that people buy every five or seven or 10 years, when their old one breaks or becomes absolutely unusable. Sort of like big-screen TVs. Some of those PCs will be notebooks, but people won’t use them portably as much as moving them from room to room around the house.

For everything else, people will buy tablets. The second (and third, and fourth) computer in every house will be a tablet. Every kid’s first computer (after their smartphone) will be a tablet. If you take a computer on vacation, it will be a tablet. Eventually, the computer most of us take on work trips will probably be a tablet, too. (Whether it runs Windows, OS X, Android, iOS, or something else — that remains to be seen.) 

Cue the trollish, angry, pigheaded, and short-sighted comments! Oh wait, I don’t have comments :)

Rachel Feltman on the possibility of using magnetite in the future instead of silicon:

Researchers showed that magnetite’s on-off electrical switch could be flipped in one-trillionth of a second—thousands of times faster than in transistors used currently. In theory, a computer made with magnetite chips instead of silicon would be that much faster than the machines we use today. But since magnetite has to be cooled to a chilly -190 °C (-310 °F) to lock its electrical charges into place, it’s not going to end up in your computer anytime soon.

The far off future.
