Supposedly the RAM is soldered onto the motherboard. I've heard mix-messages, but the Apple person on CHAT confirmed it. However he could be wrong too.
I guess we'll find out soon.
If it is soldered, that is a sad day indeed.
Soldered. From the Apple Store page for the 'mini: "Memory This Mac mini comes standard with 8GB of 1600MHz LPDDR3 memory. Please note that the memory is built into the computer, so if you think you may need more memory in the future, it is important to upgrade at the time of purchase."
