Great Portable Entertainment Gadgets

SpectraVision, begone! In today's high-tech age, there's absolutely no reason to rely on prepackaged and overpriced entertainment when you have downtime on the road. The next time your hotel's selection of third-tier basic cable channels fails you (we bet you won't have to wait long), check out one of these far more amusing options.

Bowers & Wilkins P5 Mobile Hi-Fi Headphones

British speaker shop Bowers & Wilkins just released these super-comfortable on-ear headphones, and they're perfect for taking on the road. Not too big and not too bulky, they offer exquisite sound while locking out the rest of the noisy, brutish world. Their stylish, retro good looks are just the icing on the cake.

Slacker G2

Slacker is a simple Internet radio service that lets you customize channels to your heart's content, and the G2 enables you to take those stations with you, even when you're not connected to the web or a PC. The G2 downloads songs (up to 2,500 of them) in bulk whenever you're at home, then lets you play them back whenever you're in the mood, no matter where you are.

Netflix for iPad

The iPad makes for a fun diversion as a video-game player, a solid way to browse the web and an oversize tip calculator-but one of its most useful tricks is in the entertainment realm. Anyone with a Netflix account can use the iPad to view full-screen streaming video of any of the thousands of selections available through the company's Watch Instantly service.

Flip SlideHD

Pocket camcorders are legion now, but Flip-which originated the category-has upped the ante once again by adding an enormous touchscreen to the back of its device. It's not just good for taking videos, but it also works well for watching them, with a screen that slides out and up, letting you turn the camera into an impromptu mini-playback monitor.
