One of Apple's best little talked about products
The Airport Express Base Station is one of Apple's best products that has flown under the radar, for the most part. I used it heavily as my main wireless router for over 3 years, and had an HP laser printer and digital AV receiver hooked up to it. It could handle all three tasks (sending internet data, printing, and streaming through airTunes to my stereo) simultaneously without a hiccup. My new airport extreme base station has taken over the internet routing duties, but still use the Express for printing and streaming music via iTunes and Airfoil. If and when I get an Apple TV, I will again set up the Express as an extender of my wireless network, and attach speakers so I can fill the apartment with music. If I don't need it for that purpose, I can throw it in my laptop bag and use it to set up a WiFi network if needed in places that only have wired.
What a handy device!
I was also wondering if the iPhone can be charged through the USB port on the Express. Has anyone tried this? If so, it would be an awesome iPhone accessory, since iPhone can take advantage of WiFi and the Express can create a small WiFi network in a wired-only environment.
