So, I've just ordered a macbook pro 13 with upgrade to 500 gig HDD and now i'm second guessing not going with the 128 SSD. Should I cancel and go with the SSD? I don't like having external drives (traveling) so is the speed difference that great? Simply put, should I get the SSD and deal with packing drives in suitcase or stick with the 500 HDD? I mainly am not a heavy user but I do plan to edit video.....does this make a difference?
