I ordered a mac pro with 16Gb. Ship date says March 24th. Don't really care how long it takes, I am excited though. Some people are getting stock machines now. What gives? I work for an electronics manufacturer. When we release a new product, we ramp up on everything to meet demand. Manuals, DVDs, PCBs, people, all the electronics to build the hardware we produce (ram included) are purchased/produced in massive amounts to meet demand. And we do. Memory on backorder is a lame excuse for a company like Apple. What is the real story for the delay? Are there cooling or stability issues with 16Gb+ of ram? Seems more likely than backorder to me.
