The Wall Street Journal's Walt Mossberg reviews the Creative Technology Sound Blaster Wireless music system: Mossberg is very up on the device, which avoids some of the weaknesses of similar Wi-Fi-to-audio adapters by having its display built right into the remote control.
(Mossberg complains about having to enter a hexadecimal encryption key into the Sound Blaster software to attach it to his protected network. He speaks for all home users when he writes, No normal consumer knows what "Hex" is, and companies should stop expecting them to use it. On the other hand, when he says that the key is rendered in an arcane and obscure kind of techie code called "Hexadecimal" he's just being crotchety. Hexadecimal is just base 16: 0 to 9 and the letters A to F. Fortunately, WPA will replace the hex-interfaced WEP system eventually.)
I saw a similar device, Slim Devices's Squeezebox, at Macworld Expo last week. The Squeezebox has wired and wireless interfaces, a nice remote control, and a two-line bright LED display. It plays MP3, Ogg Vorbis, and WMA (among other formats) with the jukebox running on a Linux, Windows, or Mac system.
