Twitter is rolling out new profile header photos to their users. The new option is very similar to Facebook's Timeline photo, in that it appears in a larger area along the top of your profile page.

Before, you would only have the small avatar image to work with when representing yourself or a brand. A larger photo on the profile page helps convey interests or services more clearly. Ready to add one? Just follow these steps:

Step 1: After logging in to your Twitter account, click on the Settings cog in the top right-hand corner and choose Settings.

Apple has once again been cleared of infringing on patents held by Mirror Worlds.

In a ruling posted today by the U.S. Court of Appeals for the Federal Circuit in Washington, the court upheld (PDF) a lower court decision from April 2011, which sided with Apple.

Mirror Worlds originally accused Apple of infringing on its patents with features included in its Mac OS X operating systems going back to 10.4 "Tiger," as well as in its iOS devices including the iPhone, iPod, and iPad. The company, which was founded by Yale University computer-science professor David Gelernter, … Read more

When a hot Apple product hits the market, it has a tendency to spur a cottage industry of accessories. The MacBook Air is no exception, with several companies making MacBook Air cases and covers.

Since the Air's design hasn't really changed in the last couple of years, most of the cases, covers, and sleeves that worked for the older 11- and 13-inch 2010 and 2011 models should work with the updated 2012 MacBook Air versions.

As always, feel free to make your own suggestions for cases and covers you like and we'll consider adding them in the next update.

The new iPad -- or the iPad 3, as I incorrectly like to call it -- has been out for a while, but the new cases keep on coming.

If you've already seen an older version of this list, I apologize, but the good news is that it's been updated.

As most people know, Apple barely changed the design of the third-generation iPad and a lot of existing iPad 2 cases fit the iPad 3. While a few of those iPad 2 models are represented in this round of top cases and covers, I did my best to include plenty of new models, as many accessory makers have refreshed their lines in the last few months. … Read more

Apple has some ideas up its sleeve to make its Smart Cover, well, smarter.

The U.S. Patent and Trademark Office today published an application Apple filed last year related to a Smart Cover boasting a "thin flexible display" that "greatly enhances the overall functionality of the tablet device."

According to the patent application, the cover would come with a connector that would attach to the tablet to draw power. Once connected, the Smart Cover could be used to "present visual information" and work with the same touch technology found in a slate's … Read more

Editors' note: This post was updated December 21, 2012, with five new products, including cases from Aduro, Covert, Samsung, Sena, and Urban Armor Gear.

The Samsung Galaxy S3 has quickly become one of the most popular Android smartphones, and like the iPhone, has spurred a cottage industry of cases and covers.

In boiling down the best of what's currently out there, I tried to provide a good mix of well-designed, affordable cases with more expensive models that offer some unique attributes.

One thing to watch for when buying cases these days is that you can come across pricier products … Read more

I know e-books are convenient, but I just can't tear myself away from running my fingers down the spines of real books and listening for that crinkling sound of a fresh hardcover bending open. I like the way they look. I like the way they feel.

My iPad may finally get that same sort of love if Out of Print's new Kickstarter project meets its goal. Backers will have their choice of 10 different classic literature book covers to adorn their Kindle Fire or iPad 2 or 3.… Read more

Has Google's Nexus 7 borrowed its magnetic personality from the iPad?

As detailed in the YouTube clip online and below, a curious Nexus 7 user ran a magnet along the edges of the tablet as the device was asleep. After the user pulled the magnet away from the lower left edge, the tablet's screen came to life. And when the magnet was placed in the same spot, the tablet went back to sleep.

That behavior mimics the process used by Apple's Smart Cover, which turns the display of the iPad on as the cover is pulled away … Read more
