Even uber-organized folks such as myself occasionally find themselves caught up in 16 hour days. I haven't had much time for Mac geekery as I dig out of this hole but can give a very short account of hooking up the Time Capsule.
I had almost no time to look at it but decided to give it 15 minutes last night. In that time, I was able to set it up and configure (with the new Airport software) the old router into bridge mode so I am now running dual "N" and "G" networks. I tested the over-air TimeMachine backup and get about 10 gig per hour. I got some sleep and found it had backed up 60 gb while I slept. Life should be more normal by tomorrow night and I'll have more information then.
