Summer's almost officially here. Whether you're traveling or just relaxing at home, these mobile devices can help make your leisure time more fun.

Smart phones, tablets, and laptops do lots of things well, but providing great sound quality usually isn't one of them.

With smart-phone theft reaching epidemic proportions, a coalition of more than 50 law enforcement agencies, scholars, consumer advocates—including Consumers Union, the advocacy arm of Consumer Reports—and others is demanding that smart phone makers add a 'kill switch' (a mechanism that can shut down a device remotely) to phones in order to decrease their attractiveness to thieves.

Whether you're taking an epic vacation or staycationing, the right apps can help make your summer more fun, and safer, too. We found five that we love.

Eager to get your paws on a new Microsoft Xbox One or Sony PlayStation 4 game console this fall? Walmart.com is already starting to accept pre-orders for the new systems, which will compete head-to-head this holiday season.

AT Sony's E3 event last night, anticipatory gamers got their first sighting of the new console, which had been announced at a February press conference sight unseen.

All-day battery life is coming to the MacBook Air, Apple announced today during its World Wide Developers Conference. The new laptops use the latest processors from Intel, the fourth-generation Core processor known as Haswell ULT, and one advantage those processors bring is longer battery life.
