Well, I just finished installing my new AirPort Extreme base station. This is the one shaped like a Mac mini. The new software is very nice. They added the client signal strength graph feature, something that used to be there, then wasn't, and is now back again. They've also added link status lights to the ports on the back (although no indication of connection speed).
There were a couple of things that caused a fair amount of difficulty. One was that the new admin software has been renamed. The old one was called "AirPort Admin Utility." Thew new one is "AirPort Utility." I kept trying to upgrade my software before I realized the difference. When I was on the phone with Apple tech support, the agent told me this was a frequent source of confusion.
The other problem I had was that Comcast's cable modem seems to not assign a DHCP address to a new MAC address without being rebooted (this is what initiated the aforementioned support call). The AEBS behaves as if it can't get a DHCP address from Comcast, which is exactly what's wrong. The fix (in my case) is to unplug the cable modem for 30 seconds or so, and plug it back in. (Note: the Apple support agent wanted me to unplug it for 5 minutes, but I told him I'd try 30 seconds firstâ€”it worked).
I have yet to hook up a drive, the whole reason for getting it in the first place. I want to find out if they've improved AFP enough to where applications like SuperDuper! can back up over the network without needing to create a disk image first.
Now, to get an MBP with 802.11n networking in it...
