Windows Mobile Network Analyzer PowerToy

After recently having purchased a Cingular 8125, I am finding it can do a lot of things better than my previous Siemens SX66 could. Today, I see the Windows Mobile Network Analyzer PowerToy at the Microsoft Download Center, and I wonder if anyone has played with it and is planning on posting screen shots of it. Currently, I am using Aspecto Software's WiFiFoFum to search for wireless networks and I wonder if I really need the Network Analyzer PowerToy.
