I do better with 3.5" - read time is better.
The backup silliness seems to have hit the Mac community as well of late. There's strange bug going around - one that's pretty nasty. No one is really certain how to duplicate it, but if you allow a guest login (all Snow Leopard), and login as the guest and then back as (you) in some kind of succession, your real account will get completely wiped. Completely. It's a simple fix, don't allow guest logins on your machine - but you should see the threads at the Apple forums: "I can't believe this ... what's wrong with Apple? I've got years ...
YEARS of files that are now completely gone with out any backups ... just how stupid are they?"

Forgot about that old editor ... didn't we write most of Prospect using that?
