Suggestions for first usage of SD

[cmeinck]

How about this as a strategy:
- Keep my Powerbook clean (OS, Applications)
- Pick up a small, portable 80GB or so FW drive that contains my "everyday" files (MP3's, Current works in progress, etc). Connect to the Powerbook when doing my work. The portability will allow me to travel with the drive.
- Partition the 250GB FW800 into 3 partitions

1. Powerbook 15" (contains OS and App's)
2. Portable Firewire Drive with all my data (MP3's, Works in Progress, Documents)
3. My wifes 12" Powerbook (OS, All of her files)

Thanks for your help. If this sounds crazy or if you have a better suggestion -- please let me know.
