Top New Gadgets: New Nikons, iPhone Speaker Docks

Denon Cocoon iPhone Speaker Dock

Sure, you can jack in an iPod or iPhone into this stylish 100-watt speaker, available in black or white. But slide in the dock tray, which displays the name of the track, and listen instead of Internet radio (via an Internet connection, of course) or music from a connected USB thumb drive. It's also AirPlay capable, which means you can stream music to it from iTunes on either a Mac or a Windows PC. There is a full-size Cocoon (pictured, $600) and a 25 percent smaller version ($500).
