Airport Express...More Impressions

I have had the Airport Express now for a few months and been using it a pretty good amount. I finally settled on using it connected to my stereo in conjunction with my existing Microsoft MN-700. I had to change the wireless channel on one of the devices to use them sitting right next to each other. I read this in a forum somewhere that I can't find the link to right now. The wireless channel I guess should have been obvious, just like a cordless phone, but I just never had to do this before so it wasn't obvious to me. One of the things the AE was touted as was a portable network solution, and I have really been using it like this and it rocks! First I took it to a friends house to use their broadband with the iBook. This worked very well once I reset AE to wipe out my existing home configuration, which was configured to join a wireless network, not create one. Then I took it to the Reno Hilton and plugged it into their ethernet connection in the hotel room. This worked really well, as I could use the iBook from an adjoining room flawlessly. I used the same configuration from my friends house without incident. Good thing I had the extension cord from the iBook that is interchangable with the AE since the Ethernet connection was nowhere near a power outlet. Here is a tip though, if you setup AE to use the 'net access in the hotel room, don't disconnect AE and use your laptop directly or you might get double billed. A lot of hotel rooms authorize based on MAC address. I switched to the Ethernet port on the iBook to see if this would happen and it did, but the hotel was kind enough to wipe out the double charge and all other Internet charges for my "inconvenience". Sweet!!!
