I'm looking for a portable FireWire enclosure to use as a backup disk and/or mobile storage. Since portability is a huge factor, a bus-powered device is preferred. I will be using it on my 12" & 15" Powerbook G4 and preferably also like to boot from the external Firewire disk. Anybody got any experiences they can share with the following runner-ups or any other suggestions ?

Plus speed-wise it won't be as performant as FW800 or am I wrong in my assumption ?
