For a mere $50, the palm-size Roku LT lets you stream high-definition video from the likes of Netflix, Hulu Plus, Pandora and other sites directly to your TV. The high-end Roku 2 XS costs $100 and comes with nice extras such as 1,080-pixel video, a motion-sensing controller and the full edition of Angry Birds so you can partake in some big-screen pig-toppling action right from your couch.
8. Apple 13-In. MacBook Air
Apple has revamped its razor-thin MacBook Air notebooks to include backlit keyboards and new Intel processors paired with solid-state storage for more speed and battery life. Better performance with fewer trade-offs means there's a lot to like about the 13-in. version, which starts at $1,299 and features a high-resolution 1,440-by-900-pixel screen. Oh, yeah, and it's still just 0.68 in. thick and weighs less than 3 lb.
9. Sony PlayStation 3D Display
Sony's foray into 3-D gaming gets a running start with its 24-in. 3-D-capable monitor. Reasonably priced at $500, the display works not only with PlayStation consoles for 3-D gaming but also with other compatible 3-D sources such as cable boxes and PCs. But the coolest feature of Sony's 3-D display is SimulView, which lets two players go head to head by simultaneously beaming to each player's glasses a separate full-screen picture. Goodbye, clunky split screens. Hello, insanely realistic points of view.
10. Motorola Atrix 4G with Lapdock
The Motorola Atrix 4G smart phone gave us a glimpse of where computing is headed. Released in February, the Atrix, which costs $200 with a two-year contract, functions as a fairly standard smart phone on its own. But when you popped it into the Lapdock (you could buy them together for $500), the result was a laptop-style computing experience with a full Web browser. Judging from the Atrix's potential, the question is no longer whether but when our phones will become our only computers, hopping from laptop docks to desktop docks to in-car docks and who knows where else.
