Daniel's reply intrigues me.

With external drives (or other devices for that matter) is USB less reliable 
than, say, Firewire? (I know a bit about Firewire having a controller...my 
experience with Firewire is that it is faster but I don't know that I've had 
reliability problems with it.)

Is there a distinction between using an external USB-connected hard drive for 
_data storage_ versus using it to store the operating system?

Is the NSLU2 doomed to second class status if running with, say, Debian where 
the OS is on the USB hard disk? (This considers that a native NSLU2 runs from 
its on-board OS using the external USB drive just for storage.)

Just curious about potential lessons learned.
