Over on Gizmodo there's a post about the new SMC SMCWRK-G, which is a portable wireless access point similar to the Airport Express.

SMC has announced a new portable wireless access point a la the Airport Express. They're calling it the "EZ Connect™ g 2.4GHz 802.11g Wireless Traveler’s Kit SMCWTK-G," but we'll probably just call it the SMCWRK-G or Dance Panda Mandy, as it suits us. For what it lacks in good looks it makes up in features, as the SMCWRK-G can do everything the Airport Express can do and more (save the iTunes streaming), including act as an Ethernet bridge. It might not be attractive, but it's $30 cheaper, ringing in at just $100.

Perennial Wi-Fi smart guy Glenn Fleishmann weighs in with a little more detail at Wi-Fi Networking News.

The Airport Express is also a print server, which SMC isn't listing as a feature for this device. This looks like it is more useful if you just need wireless access when you travel. But for $30 you're losing a bit of functionality, and you need to carry around a power supply to go with it.
