I was looking for a better option than Bluetooth for a wireless speaker. Most AirPlay speakers I've seen are quite expensive, but I saw this one at my local Apple Store and thought I would give it a try. It's much more affordable than the $350+ price of many of the other brands. So far I'm very happy with it. I had it set up and working in just a few minutes. The sound is really good, but I'm sure it won't hold a candle to a B&W or Bose. Since I'm no audiophile, it's good enough for me in my home office. Plus, it has a rechargeable battery built in, so I can easily move it from room to room if I want.
Others have posted reviews mentioning problems with networking. I'm using an Apple Time Capsule as my router with 802.11n and WPA2 Personal security. The instructions say that you can ONLY use this speaker on a network with WPA or WPA2 security, and that it won't work on WEP or WPA/WPA2 Enterprise networks. iHome should really put this on the outside of the box.
If you want a low-cost AirPlay speaker with decent sound, I think this is a great buy. Just be aware of the WiFi network requirements before you buy.
