Just wondering, I have a stock machine 09 MBP 13" (for the most part) that is only 2 weeks old or so. I have adjusted a few settings and such and I do not have an external HD yet and the only thing I have added is Firefox (for now) and the updates of course minus the firmware 1.7 since I heard people had problems with that. I kept it this way knowing that SL was going to be coming out soon. So, I was assuming if nothing else (or if something goes wrong) I could always just reload everything from the restore discs which essentually would act as my backup. so I do not have any mission critcal settings or items that are not hard to redo I do intend on getting an external at at some point. Am I right in assuming this? I know it would probably be more of a pain to have to go that route but I figured it is pretty much the same. any thoughts? of course I would like to think I will not have any major probs to begin with.
