As a Unix engineer and closet Mac user, I was going to give serious consideration to using Mac OS X as my desktop OS (and ignore the cracks from my coworkers). The beta seems fine enough to replace NT, but then I realised something pretty important. There are no serial ports on Powerbooks! How am I going to get a console connection? Does anyknow know if there is a product on the market that provides a serial connection from say, USB?
