> Don't want to deal with the logistics of lots of SKUs? Don't sell them. Trying to upsell people is a money move. Selling a SKU where the 80+gb OS is like 40% of the disk is a good SKU to cut.

This isn't a profitable move from Apple's perspective - they try to keep the base unit at about the same price across generations. That's what happened when they moved from 8 GB of ram to 16 GB.
