Rokland recently unveiled the RokAir WiFi USB adaptor for Macs using OS 10.3 or higher. The RokAir is billed as an Airport alternative, and uses 802.11b and g to communicate with routers. Rokland says that users can expect to see a 100- to 200-foot area of reception from the device, which is flash drive-shaped and simply plugs in to a vacant USB port. The Rokair comes with a built-in heatsink, so that it can be used for long periods of time without overheating. Rokland is selling the adaptor for $30, plus shipping, and is available now.
The Rokair is compatible with G3-based Macs, all the way up through to the current Intel machines, and works using the built-in Airport drivers in a Mac. Many PowerPC users don't have access to wireless technology due to Apple's discontinuation of the original Airport Revision E card, since the Airport Extreme card uses a different connector.
