enjoying that Rev. A speediness for some time now (in certain locales, at least), the Mac faithful have been fairly well shut out up until now. Thanks to Sprint and Sierra Wireless, all that changes today, as the Seirra AirCard 595 PC Card now works in OS X 10.4 or later. The free Watcher Lite 1.0 software is currently available from Sierra's website, but before you go dashing out to pick up a card, you will still need a Windows-based machine to activate the device or have it pre-activated before heading into your Mac. Furthermore, don't plan on utilizing that ExpressCard slot either, as the only supported card thus far rocks a PCMCIA interface. Nah, Macworld hasn't hit full swing just yet, but this news is a real fine way to get things rolling.
