In the old days, radios were big pieces of furniture, with the family gathering around to have a listen. That was when milk was delivered directly to your door, but in this new millennium there's no reason to be so tethered to anything to listen to music. Sony's Vaio WA1 Wireless Digital Music Streamer will let you share your audio files from a PC to any room.

The standalone device lets you listen to your tracks through a wireless home network (or a peer-to-peer connection, if you must), and the WA1 is compatible with Sony's ATRAC digital music format, among others. Those other formats are unprotected AAC, MP3, and unprotected WMA files. Note that the key word is "unprotected," so PlaysForSure files shouldn't be expected to, um, play for sure. The stereo speakers can pump out 8 watts of sound, and it doesn't hurt that it looks pretty hot.

The WA1 has 128 MB of onboard storage for tunes and up to 4 hours of battery life, so you can store up about one CD's worth of music when you take it on the go. The Wireless Digital Music Streamer will be available later this year for about $350. But can you put a price on cutting the cord? — Peter Suciu
