This is a follow-up to last week's "Before you buy a sound bar speaker, read this" post, but this time I'm setting my sights on expensive, $400-plus iPod and Bluetooth speaker "docks." They have built-in limitations common to all single-speaker systems. They might have two sets of speaker drivers housed in a single cabinet, but when the drivers are just a few inches apart, "stereo" sounds more or less like mono. In the quest to make these speakers as sleek and lightweight as possible, bass and dynamic range capabilities are limited, compared … Read more

People love sound bars for a lot of good reasons: they eliminate most of the wiring and setup hassles associated with traditional 5.1-channel home theaters, they don't take up a lot of space, they are less expensive than subwoofer/satellite packages, and since most sound bars are self-powered, you don't need to buy an AV receiver. A skinny sound bar positioned under a sleek display is certainly a more appealing solution than a 5.1 or even stereo pair of speakers. There's just one problem: sound bars can't fill a room with sound nearly as well as separate speakers can.… Read more

Texas Instruments is officially getting out of the consumer smartphone business, as major phone suppliers like Apple turn to internal chip designs.

"TI...will reduce costs and focus investments in its wireless business on embedded markets with greater potential for sustainable growth. Cost reductions include the elimination of about 1,700 jobs worldwide," TI said in a statement today.

While TI didn't mention any names, one of the most telling statements alluded to companies that are now designing their own chips. That would include Apple, which designs processors for its iPhone.

"Large customers are increasingly developing … Read more

Apple has become a formidable chip designer with its A series chips. And that's probably not good news for Intel, says a chip expert.

I asked Nathan Brookwood, principal analyst an Insight 64, about the shifting dynamics of the relationship that began in 2006, when Apple dropped the PowerPC for its Mac line.

Brookwood said, in effect, that if you reduce the relationship to the fact that Apple must continue to pay an "Intel tax" for chip designs it doesn't control, the future is not very cheery.

When Apple abandoned its long-standing use of PowerPC chips in favor of those from Intel, Steve Jobs said, "It's been 10 years since our transition to the PowerPC, and we think Intel's technology will help us create the best personal computers for the next 10 years." Eight years have now passed since that moment, and recent developments suggest that Apple may abide by this statement and move to a new architecture within a few years. But not only is Apple looking to new hardware, it is also preparing plans for its operating systems.

Apple is starting to release some scary-good silicon. But can it muscle out Intel?

Last decade, the question was, will Apple go Intel? After years of speculation, that finally happened in 2006, when Apple dropped the PowerPC for its Mac line.

So are we now on a similar trajectory, as a Bloomberg story speculates, with Apple eventually evicting Intel from its Macs and using its own internally developed processors?

A quick look at the latest Apple silicon shows the company is on the right track. The A6X is a serious piece of silicon that makes the newest gen 4 iPad … Read more

After researchers at the University of Pennsylvania's Perelman School of Medicine called on the general public to find as many of Philadelphia's estimated 5,000 automated external defibrillators as possible, more than 300 "citizen scientists" stepped up and located 1,429 of them in more than 525 buildings across the city.

The eight-week crowdsourcing contest, called MyHeartMap Challenge, is part of what the researchers hope will be a national effort to catalog as many AEDs as possible and develop an interactive app of the registry so that laypeople can act quickly in the event someone nearby … Read more

At its silicon core, the fourth-generation iPad is hardly an incremental upgrade, according to chip analysts.

The new iPad's A6X chip packs a brand-new graphics engine that boasts a serious step up in horsepower from the third-generation iPad's A5X.

"Nothing's incremental about this. The A6X is one massive processing machine," Jim Morrison, a product manager at Chipworks, which does reverse engineering and patent-infringement analysis of semiconductors and electronic systems, told CNET.

Chipworks posted an analysis of the A6X's circuit layout today.

Apple's newest chip is a full 30 percent larger than the A6 … Read more
