@danfrakes You must have small documents...otherwise even Excel '04 is much quicker than Numbers.
I also like BBEdit's scripting option to open windows read-only.
Thanks for the Drobo info everyone. I don't think it really makes sense for me, but it sounds pretty neat.
What happens if a Drobo dies? I assume you can't read the data using regular enclosures, but can you just stick the drives in a new Drobo?
