Time to take the plunge. The price has dropped and I get a free wifi card for my camera so what the heck.
UPDATE: After a day of hell, the Drobo has worked flawlessly for me (hint: never plug it in to the front Firewire ports as there is not enough power there. It must go in the back FW or USB ports). I have it set up as a media center repository with about 2TB of data right now (and much more coming soon, as I move some other data onto it before the big move)
