Considering how penetrating each and every one of Apple's devices has been in the personal tech market, it's no wonder iTunes continues to make loads of money. It wouldn't happen without the individual contribution of each of iTunes' millions of users. But just how much app, song and movie money does each person contribute to Apple's world domination each year?

Doesn't it seem like every allergy season seems to be the worst ever? So when I was offered an opportunity to review the ZŌN Personal Air Purifier, I leapt at the chance. Initially previewed at the New York International Gift Fair 2013, the ZŌN stood out on the show floor, yet inaudible amongst the din of the show floor.

Are you reading this on your smartphone or tablet right now? Do you even still use a laptop or desktop computer at home? There's a growing group of us who hardly touch a computer any longer, happy to rely upon our handheld devices for all our computing needs.

A few years back a good friend of mine, a dedicated gamer who competes competitively, built himself a head-to-head gaming cabinet to keep his fighting game skills honed from the comfort of his garage.

Just a few hours ago Larry Page concluded the keynote for Google I/O 2013.

The color customization option joins last month's 2.0 software update, which optimized battery life two additional hours and fixing dropouts and interruptions at greater distances while streaming from an iOS 6.1 device. Sounds like the perfect audio companion for a picnic or dining al fresco now warm weather has become the rule, not the exception.

Smartphones have wiggled their way into practically every aspect of our lives, and in the process, thanks to the utility of the wide selection of apps available at our fingertips, have replaced books, newspapers, GPS units, digital cameras, gaming devices, maps, and countless other things we once hauled around. So why not our house keys?

Light fixtures can be changed. Colors can be painted over. Ugly floors can be covered. They're not all easy projects for renters who've found themselves in apartments cramping their style. But they're all do-able, and importantly, reversible. Just like this solution for covering ugly appliances with removable peel-and-stick wallpaper.
