Tablets and smartphones are making music more fun for musicians and nonmusicians alike. These devices--mainly iPhones and iPads at the moment--have brought about a wave of innovation in tuneful apps. Here are some of the coolest ones out there.

You know those "Alex P is listening to Sleezin' by Freak-Z on Spotify" messages you always see in your Facebook ticker? You're going to start seeing many more of those, and not just ones about your friends' music tastes.

PC World readers like their iPhones. More survey participants own this model than any other phone, and an unusually high proportion of them praised its durability, ease-of-use, design, and camera quality in our 2011 Reliability and Service survey.

Were he speaking for any other company, his statement would have smacked of PR bluster, but Cook meant it literally: Apple’s suppliers can’t make the components for the iPad 2 as fast as Apple can sell the device.

By now you've seen all the ads pitching wireless companies' new 4G mobile broadband services and devices. But beyond all the buzzwords and hype, which companies can reliably provide next-generation speed?
