BusinessWeek on AirPort Express

Alex Salkever of BusinessWeek covered the AirPort Express in his column, but there were a few things in it that I found puzzling.
First, and biggest, he wrote:

A new piece of software, AirTunes, promises seamless synching between a computer — PC or Mac — and any Wi-Fi-ready speakers within range via the Express router… Alternatively, you can buy a wireless connection kit and plug a stereo directly into an Express to connect it to a desktop with a Wi-Fi card.

Actually, the AirPort Express (or the “AirPortable”, as I’ve taken to calling it) has two audio outputs built in: a digital output for S/PDIF and a mini-jack. If you have conventional powered speakers, you just plug ‘em in. You can use the S/PDIF output to plug the unit in to your stereo or A/V receiver, too. Apple does sell a connection kit, but it’s nothing more than some (overpriced) Monster audio cables. While there may be vendors selling “Wi-Fi-ready speakers” (I couldn’t find any but admittedly I didn’t look very hard) I’m not sure that’s the target device Apple has in mind.
Another nit: AirTunes doesn’t synch anything to anywhere. It merely encrypts and streams the currently playing iTunes selection and sends it, using Rendezvous, to the selected AirPort Express. Saying “seamless synching” implies that your music library is synced to the Express device.
Next, the article doesn’t mention one of the really cool features of the Express device: it can extend the range of an existing AirPort Extreme base station by acting as a wireless bridge (similar to the trusty Linksys WET-11). This is a killer feature, since a) it’s trivial to grow your network range by plugging one in and b) it only works with AirPort Extreme base stations– thus helping to justify their inflated price.
