My superdrive died on my 2 year old MBP. I have been waiting for a few months now to get an extra $300 to replace the drive (price quote of a local authorized shop). I would like to replace my MBP for a new MB later next year and keep the old one for my wife. In that case, I should probably save the $300 towards the purchase of the new mac. Meanwhile I have been transfering stuff I need to burn to my iMac at work via wifi or USB drives. I was thinking of getting an external USB DVD drive just for the occasional burn. My question is, would I be able to reinstall (in case I needed) the OS form an USB DVD drive? I believe that from a firewire drive I might, but the chances of finding one here are very slim. BTW. My drive wont read or write DVDs or CDs, originals or burned ones. ANy thoughts? .
