c|net reviews SoniqCast's Wi-Fi-enabled MP3 player: The device gets 7.7 out of 10 points for its good featureset, small form factor, and easy Wi-Fi configuration. The retail price at Best Buy is $300. Transfer speeds are quite slow -- just a few hundred kilobits per second -- whether via USB 1.1 or 802.11b Wi-Fi. WEP support is built in; WPA support due later this year. It has a FM receiver for that older form of wireless music transmission. It stores 1.5 gigabytes.
