I've got my TC doing just about everything I wanted thus far, with a couple nagging things. I've attached a USB hard drive, and it shows up on my Mac, but not on the PC (running Vista). If I run Airport utility on the PC, I can see that the drive is recognized and attached, but I can't figure out how to actually access the drive. I tried "add network drive" but couldn't get it to show up. I don't actually remember how I got the TC itself to show up, I do recall it didn't work at first. On a side note, I had a rather hit or miss time with the TC setup. Some stuff was incredibly easy/quick. Other misc steps seemed off but fine when I rebooted. Interestingly you're never told (that I saw anyway) to restart/reboot the computer, but it seemed like it was required (for me anyway) in a number of instances. Another odd quirk is the TC doesn't seem to show up on my iPhone, haven't quite figured that out yet.
