so every time i upgrade my MBP i go and uncheck the 1.7 firmware. should i just delete it? is it never going to work with the after market HDs? Is the 1.8 out and im not getting it b/c i havent dl'd the 1.7? also, my brother is going to be buying a new 13" mbp very soon. he wants to get the 500gb scorpio blue just like i did. Is he going to be able to? do the new ones come with 1.7? Thanks.
