Logitech has been in the home audio business for a long time, though much of that has been centered on computers, and more recently, mobile devices. The acquisition of Ultimate Ears five years ago was likely a move in that direction, now that Logitech sees how hot the headphone market currently is.

Go big or go home is the old adage, and Samsung seems to have taken it seriously, offering phones in various sizes to cater to just about everyone and anyone. The Galaxy Mega is at the top end of the scale as far as size goes. It’s a monstrous device with a 6.3-inch display, almost like a mutated Galaxy S4. The extra screen real estate and affordable price point make the Mega an attractive proposition, but will size really matter once you see what it can do?

Hollywood special effects have wowed audiences for a long time now, going back to the 1980s, and though the computer-generated animations seemed destined for the silver screen and video games, you actually do have the opportunity to play around with them using your smartphone.

If you have a lot of music on your iPhone, and you tend to like how a live concert sounds, there’s an app that puts the two together in a unique way. LiveTunes is an iOS app that simulates the sound effects of a live concert for tracks you already have stored on your device. Imagine how a song recorded in a studio would sound if it had all the elements of a venue, audience and acoustics. That’s what LiveTunes delivers with particular coolness.

Streaming music on your smartphone or tablet can be such a satisfying experience because the songs keep coming, they don’t cost a thing and you tend to discover tunes you may have otherwise never known about. There are several popular apps that do all that, but there are also some little-known ones that offer plenty, too.

Everyone loves apps on smartphones, perhaps even more than the music or photos stored on those devices, which is a big reason why you might have run into a brick wall with your internal storage capacity. Giving your phone a good cleaning can help free up valuable space you need now or will need later.

Aereo CEO Chet Kanojia would probably be one of the last guys to get a dinner invitation from any of the big TV networks or cable companies. His upstart company has irked them so much that Fox wants to take their ongoing legal battle all the way to the Supreme Court, while they continue to move forward with plans to fan out across the country and try to chuck some dirt onto older methods of live TV consumption. In a one-on-one interview with Digital Trends, he tells us why and how.

If you were shopping for a TV three years ago, you were probably bombarded with all kinds of talk about how cool 3D was and how it was the “next big thing” in TV viewing. Movies and sports would never be the same again, with characters and players popping out of screens and into your living room as if they were right in front of you. It’s now 2013, and 3D is but a footnote that barely measures up to smart TV features and the looming 4K Ultra HD resolution TVs. It all begs the question: Why didn’t 3D ever take off the way it was expected to?

For Samsung, $30 million is probably just a drop in the proverbial bucket, but spending that cash to acquire Boxee and bring in all 45 staff members is an investment — and perhaps an aggressive move to improve what it can offer consumers in the living room by taking on Apple TV and Roku.

You may not realize it, but your home is infested with little vampires. No, we’re not talking about the Twilight box set you just bought, we’re talking about your mobile phone charger, your TV, your Blu-ray player, your subwoofer and God knows how many other devices that spend at least half of their lifetime plugged in, even when you aren’t using them. So what’s the big deal? Well, it turns out these “vampire” devices are responsible for a huge amount of wasted energy; and if your inner environmentalist isn’t moved, then consider the fact that they are slowly but surely sipping money right out of your wallet. But it doesn’t have to be this way. A few simple changes can save you money, take pressure of the grid and instantly end the threat of global warming. Ok, maybe we exaggerated a little on that last one; but cutting these little suckers off is a worthwhile endeavor, no matter how you slice it. Here’s what you need to know about vampire power and how you can stop it.
