I have a question about this product: I understand, that I can play music from my iTunes library on my MBP or Ipod touch, if my stereo system is connected to the Airport Express. That is pretty cool =) Is it any different than the thing from Belkin though? And one more thing, if it can do that, I am completely blown away, and I will buy it immediately =P. I see that the AE has a USB input, so I was thinking if I can hook up my external hard drive to the AE and do my backups wirelessly? If that does not work, is there any other way to do the backups or simply use the external hard drive wirelessly? (Considering I already have an external hard drive and won't buy the Time Capsule ) Thanks a lot for the help!
