Late next month, Nintendo is set to release the 3DS, the successor to their popular Nintendo DS handheld console. Besides a few bumped specs, the main selling point of the 3DS is its glasses-free 3D display, which Nintendo hopes will give their latest handheld a leg up on the competition… most importantly by giving them a clear point of differentiation from the DS’s number one competitor, the iPod Touch.

How long will Nintendo have 3D superiority over the Touch, though? Perhaps not as long as Nintendo thinks. A new rumor coming out of Japan suggests that the next iPod Touch will have the same glasses-free 3D display found in the Nintendo 3DS, based upon Cupertino’s multiple patents for 3D related technologies.

We love Sanho’s line of HyperMac products, which allow you to juice your MacBook or iOS device with an external battery pack… but when Cupertino C&D’ed Sanho over Hypermac for using Apple’s patented MagSafe connectors, the future of the product line seemed in doubt.

We needn’t have worried. A couple of weeks ago, Sanho announced their new line of HyperMac batteries, which use Apple’s own airline adapter to connect to your MacBook via MagSafe, a solution that deftly sidestepped the legal problems.

The only problem with the new HyperMac batteries? While they’ll keep your laptop going, they won’t actually charge them… kind of a bummer.

Luckily, Sanho’s just announced a new HyperMac battery conversion gift that lets you modify your existing MacBook power adapter to not just hook up to your laptop as usual, but also to connect to your external battery. Sanho claims there’s no soldering or complex rewiring required, and that the instructions are easy to follow.

We’ve got a review copy on the way, so we’ll let you know if those boasts pan out, but we’re tentatively excited. The new batteries and the modification kit should be available at the end of the month, with prices starting at just $100.

A company has sued Apple and a number of other technology firms, alleging their smartphones and other touch-screen devices violate a patent covering “double-click input.” Apple’s iPad and iPhone were specifically mentioned because the handset and tablet allow users to “double click or double tap a visual element representing content and interact with a second version of the interactive content.”

The lawsuit by Hopewell Culture and Design asks an Eastern Texas District Court to award “adequate damages” for the supposed violations. The U.S. Patent No. 7,171,625 was first filed in 2002. Also named in the lawsuit are Adobe, HTC, Nokia, LG Electronics, Motorola, Opera, Palm, Samsung and Quickoffice.

A patent recently granted to Apple has got online observers predicting a future touch-screen MacBook laptop.

It’ll never happen. Before I tell you why, let’s take a look at the evidence.

Even if Apple thought Antennagate was overblown, let’s face it: their last attempt to put the iPhone’s antenna into the exposed edges of the device didn’t work out so well, prompting a PR catastrophe so bad that Apple was actually forced to hold an emergency press conference… something they never do.

That in and of itself suggests pretty strongly that Apple’s going to try something new for the iPhone antenna in future handsets, and if a new patent is any indication, that new approach to hiding the iPhone’s antenna may be by hiding it under the iconic Apple logo.

Hiphop star Dr Dre is suing a headphone rival for allegedly knocking off his designs.

In a lawsuit, Dr Dre charges Fanny Wang’s new headphones with knocking off the Beats Solo and Studio models. Dr Dre’s headphones are made by Monster and sold under  the “Beats by Dr Dre” brand.

“Fanny Wang’s headphones, color scheme, packaging, and overall advertising campaign directly infringes Beats’ trademark and patent rights,” says a legal letter sent to Fanny Wang, which launched its new ‘phones earlier this month.

“I can honestly say the tactics they are pulling are clearly intended to squash competition,” said Tim Hickman, Fanny Wang’s CEO, in an email.

What do you think? Look at the picture above. On the left is Dr Dre’s Solo; on the right is one of Fanny Wang’s new models. Both are folding headphone designs. Here they are in more detial:

Earlier this year, Sanho — makers of the super useful Hypermac line of batteries — found themselves in a pot of hot water boiled by Apple’s legal team, who objected to Hypermac’s use of repurposed (and patented) MagSafe cable connectors to juice up hungry MacBooks.

You can’t keep a good product down, though. HyperMac has just relaunched the HyperMac line, this time working around their reliance upon old MagSafe cables so as not to draw Cupertino’s ire once more.

In the immortal spirit of Nigel Tufnel, our 2010 Year in Review of the best in Audio gear and apps for Mac and iOS devices goes to 11.

If you missed any of these or didn’t get a chance to check them out for some reason or another, don’t fret — they each should be around to help you discover dulcet tones and make sound memories for a long time to come.

Plus, your iDJ library can be managed through iTunes. iDJ is the first true music-mixing application for iPad that both beginners and professionals can enjoy.

As we previously reported, Apple has ambitious plans to put users’ Home folders in the cloud to make them available on any machine.

The system will use the iPhone 5, which will likely include a Near Field Communications chip, as an authentication mechanism. Near Field Communication (NFC) is a short-range wireless connection technology that would turn the iPhone into an electronic wallet or security passkey. Bump the iPhone 5 near a compatible NFC-equipped Mac, and the computer will load the user’s home folder and preferences.

However, it was unclear whether users would be able to load all their files onto the host machine. After all, iTunes and iPhoto libraries can get pretty large. Loading a massive iTunes library onto a guest machine from the cloud could be a lot of heavy lifting. And how about the applications to run them? What if the host machine didn’t have Photoshop installed?

Apple’s solution is that only a subset of user’s data and content libraries will be made available, according to a source familiar with a test version of the system. Specifically:

The U.S. International Trade Commission has decided to investigate Apple’s allegations against Motorola. In October, the two handset makers accused each other of patent infringement. Apple charges the Schaumberg, Ill.-based Motorola violated six multi-touch patents.

If the ITC rules in Apple’s favor, importation and sale of Motorola smartphones could be banned in the United States. The patent spat erupted in early October when Motorola accused Apple of violating 18 patents and refusing to agree to license Moto’s technology. Apple fired back in late October, claiming Motorola had violated its patents.
