I already purchased what I wanted earlier from Apple earlier today. Bought the 2.6 i7, with fusion drive. Upgrading to 16 GB ram myself. I had the money set aside and didn't want to take a gamble and get a downgraded unit just to save a few bucks. I was considering doing fusion myself but didn't want to fuss with taking apart the entire unit. In a year or two I will take it apart (after my warranty runs out) and I'll put in a 500 GB SSD to increase my fusion. By then SSD will be cheaper as well. I think a 128 GB fusion will be all I need anyways. There really is no reason for a HUGE fusion....it's not like you can use 128 GB at a time. And it will keep moving the files around on it's own.
