Hello, I am going to be a proud owner of a new MBP 15 2.53gHz next week! Question 1: Somewhere along the line I heard that you can use another hard drive for a scratch disc for editing videos, etc. Do you do this in firewire target mode? can I use a 800 to 400 firewire adapter? will the speed be to slow if I use my powerbook 12"? Question 2: I have this PB 12" that I got dirt cheap 1 1/2 years ago and it is slowly going to crap. The keyboard stopped working except the letters do work, No backspace, delete, etc. (I have a bluetooth keyboard so this has been my work around)Also the optical drive stopped working. Locked up on me. every once in a while it will make a noise like it is trying to spit out a cd, but the slot entrance is blocked. ?? Anyways, I am not worried since I am getting the new MBP...Is this thing even worth selling? If so, how much do you think it would go for? recycle? Thanks!
