There may be life in the BlackBerry PlayBook yet.

Research In Motion's tablet saw a surprising jump in shipments in the fiscal third quarter, with the company sending out 255,000 units in the period. In the last quarter it shipped 130,000, only slightly less than the 150,000 it shipped a year ago.

So what gives? Chief Financial Officer Brian Bidulka said during an investor conference call today that there was strong "promotional activity" in North America, with RIM seeing some success with the Wi-Fi and 4G versions of the PlayBook in North America and … Read more

Besides installing an SSD to replace a mechanical hard drive, RAM upgrades are one of the more significant and beneficial upgrades you can do for a PC system. When it comes to Apple's systems, however, RAM upgrades from Apple itself have been insanely expensive, so my recommendation has always been, unless the RAM is soldered to the motherboard (as it is with the MacBook Air and Retina MacBook Pro), to purchase only the base amount of RAM and then upgrade it yourself later on.

Such was the case with my most recent Mac, a 17-inch 2011 MacBook Pro that … Read more

Penguin has become the latest book publisher to settle federal charges of e-book price-fixing, leaving only Apple and Macmillan to fight the Justice Department allegations.

In an antitrust lawsuit filed in April, federal prosecutors accused Apple and five book publishers of conspiring to artificially hike prices. The same day, the Justice Department announced it had reached settlements with three publishers but said Apple and the other two publishers had opted to fight the charges. Lagardere SCA's Hachette Book Group, News Corp.'s HarperCollins Publishers, and Simon & Schuster (owned by CBS, which publishes CNET) agreed to settle.

Penguin added … Read more

Apple has released three EFI firmware updates for some of its Mac systems that were released in 2012, which tackle a number of issues pertaining to sleep, Thunderbolt performance, and -- more relevantly to many users -- reliability of Wi-Fi connectivity.

The first update is a Wi-Fi update for all late 2012 Mac systems that improves compatibility with 5GHz-band Wi-Fi signals.

The update includes a new version of the AirPortBrcm4311.kext kernel extension. This update is specific for those running OS X 10.8.2 build 12C2034 (you can look this up by clicking the version number of OS X … Read more

There are plenty of iOS devices on holiday wish lists this year. Which means there's bound to be plenty of iOS devices under trees, waiting for anxious kids to unbox and begin using them.

On the other side of those iOS devices are parents, like you, trying to figure out how to limit the amount of spending on games, apps, books music and movies their kids (or perhaps themselves) can do in iTunes.

Today I found a feature in iTunes I didn't know existed; the ability to set up a monthly iTunes allowance for specific Apple IDs. Brilliant! … Read more

From smartphones and tablets to a $7,000 desktop, we've cracked open a lot of tech this year. And as is the tradition at the end of each year, it's time to take a look at a few of our favorites. During this special episode of Cracking Open, I'm counting down my top five teardowns of 2012.

5. Nokia Lumia 900

First on our list is the Nokia Lumia 900. Released in the spring, this Windows Phone device was Nokia's attempt to recapture some of the American smartphone market.

Unfortunately, as we discovered during our teardown, the phone's hardware just wasn't up to par with the competition. I went so far as to call it mediocre. So why did I include our 900 teardown on this list? Because it's probably this year's best example of why knowing what's inside a device is an important factor in deciding whether to buy one.… Read more

Amazon's new Chinese Kindle store is reportedly being investigated by Chinese authorities over charges that the store does not have a license to sell e-books in the country.

China's GAAP (General Administration of Press and Publication) agency requires that digital publishers operating in China must receive at least one of four licenses to publish, copy, distribute, or import ebooks, according to blog site MIC Gadget.

But Amazon allegedly did not obtain any of the required licenses. Instead, the company reportedly borrowed a license from one of its partners, which is against the law in China. Amazon did apply … Read more
