Two weeks ago when I was transferring data from my 2.0GHz mini to my 2.53GHz mini, I literally used the same FW800->FW800 cable for TDM that I normally use for my FW HDD or my FW CF card reader. The only reason I keep FW800->FW400 or FW400 cables around is that my FireWire audio interfaces
haven't been updated to FW800 connectors yet.
I certainly couldn't chain two audio interfaces through a hard drive via USB
(nor would performance be acceptable).
Why give up one of your tools in your toolset? It's not like any of the stuff above prevents you from using TDM where it makes sense.
Frankly, thumb drives and keyboards are the places where USB makes sense (where performance doesn't matter).
There are pros and cons here. You need a different adapter if the Mac has FW400 or FW800. With USB1.0, 2.0 and 3.0 the connector is backwards compatible, not just in the signaling but in the port interface.
I have nothing against FW. My comments focusing on the extra effort to migrate, troubleshoot and repair using a 2nd Mac, the extra effort to troubleshoot using an extra Mac, and the speed issues with troubleshooting using the optical Restore Disc.
If I need to fix a friend or family member's Mac I don't need to take my Mac with me. I can do it all from a device that fits in my pocket. If I need to repair my boot drive I can do it all without the need of another Mac or the optical Restore Disc.
It's all extra effort, extra HW and extra time.
For instance, I bought a new MBP recently. One I installed the SSD, removed the ODD and placed an extra HDD in its place I installed the Mac OS X using an SD Card. Then I "migrated" my system using Time Machine.
While this was going on I was able to clean up my previous MBP and box everything up nicely. There was no need to run both of them or us the slow optical disc for the installation.
edit: FW HDDs aren't always FW800 or FW400. I had one that used the 3-pin connector, but yeah, usually they are one of those two ports so you can get away with having a single adapter and single cable for troubleshooting so long as you are using a Mac with the same FW port.
