On a side note. i really hope Aplle can fix these supply issues. They are finally starting to be taken seriously again n the mainstream market and are generating a lot of buzz with there computers (security, iLife, etc.) but these supply issues are going to kill it if they can't fix it soon.
Most people looking to switch won't like waiting 2-4 weeks for a new computer that are unfamiliar with. They will likely cancel the order and buy some crappy Dell that gets FedEx'ed to them within a few days.
