Apple’s latest offering - the Airport Express is one very cool device that finally makes it easy for you (and lightweight) to share an Internet connection in a hotel room. It looks just like the size of the charger of my PowerBook. And you can actually stream music from your Mac to your Hi-Fi wirelessly. Cool! I am just waiting for the units to be available in Singapore….but looks like I still to wait a couple of weeks more.
