While Griffin's new $70 AirDock might sound like it's a contender to the wirelessly syncing WiDock's throne, don't let its name fool you. It doesn't sport 802.11x for syncing with a Mac or PC, but it does include an RF remote for controlling the AirDock, even through walls (Infrared, like in the Apple Remote, needs a direct line of sight). It also has an A/V out port for running your iPod media out to an entertainment center, but it doesn't have any kind of on-screen menu navigation like the more powerful $129 TuneCenter accessory. The other decent advantage for its price, however, is the inclusion of Griffin's PowerBlock, their compact $30 AC-to-USB charger that should be able to sync nearly any iPod with a Dock connector, as well as the 1G iPod shuffle due to its USB interface.
The AirDock is shipping now, and more details are available at Griffin's site.
