Steve Jobs was a “tweaker”: Author Malcolm Gladwell writes in this week’s New Yorker review of Walter Isaacson’s authorized biography of the late Steve Jobs that the Apple co-founder’s true genius was not in his design or his vision. It was in his editing.

Gladwell, who’s found success writing about the reasoning behind success, compares Jobs not to Thomas Edison or Albert Einstein, but to Richard Roberts — a precision-tool maker from the British Industrial Revolution who perfected Samuel Compton’s cotton-manufacturing device, the spinning mule.

Report: Apple trying Siri on older phones: Siri, the artificial intelligence personal assistant from Apple, has been the main draw for those wanting to update to the iPhone 4S.

Industrious hackers and crackers have already figured out a way to make Siri run on older iPhones and the fourth-generation iPod Touch, but now a report from JailbreakNation shares that an unnamed “source close to Apple” has found that the company is testing Siri on devices other than the iPhone 4S.

Apple TV: The techie’s wish list: A one-sentence mention of the Apple TV in the authorized Steve Jobs biography has sparked a whole lot of chatter about what, exactly, Jobs may have “cracked” about the interface of the connected television.

To make a full Apple television set, however, Apple wouldn’t necessarily have to build the TVs itself. Sanford Bernstein’s Toni Sacconaghi, Fortune reported,says that a fully-integrated television set doesn’t make sense for Apple. Would you want an Apple-branded television, or would a revamped Apple TV set-top box work just as well for you?

Google+ rolls out brand pages: Google has finally put the finishing touches on pages for brands in its social network, making the service much more valuable for advertisers.

The search giant took down pages put up by businesses (including The Washington Post) in the early days of the project because the social network did not yet have policies in place for them. Now Google+ Pages are up and running, five months after the social network went live.

Facebook’s vision of the future: Mark Zuckerberg wants to be a platform agnostic. The Facebook co-founder, in an interview with Charlie Rose set to air tonight, said that he considers two of his rivals in the “tech war” — Apple and Amazon — to be “extremely aligned” with Facebook. But Google is a different story.

“Google, I think, in some ways, is more competitive and certainly is trying to build their own little version of Facebook,” he told Rose. Zuckerberg said that he just wants to put Facebook on as many platforms as he can, a sentiment echoed by Facebook chief operating officer Sheryl Sandburg, who was also in the interview.
