The WL-330 packs a lot into a very small package. Its performance is comparable to that of full-sized 11b access points and has a feature set that can go also toe-to-toe with the big boys'.
I would have liked to see it (and every other wireless product introduced from now on) support WPA. A few other monitoring features would also be helpful, especially when setting up bridged connections.
Its inability to attach to higher-gain antennas will probably keep it out of outdoor bridging applications, but its size and packaging make it perfect for fleshing out the dead spots in home and office WLANs.
The WL-330 may not have the sex appeal of 100+Mbps 802.11g gear, but it's perfectly equipped to solve the problems that most WLANs really have.
