Hey there, So, I'm somewhat a computer geek, but really know next-to-nothing about hardware. I currently have a 15" mid-2012 rMBP that's absolutely maxed-outfastest processor, largest SSD, 16gb RAM. The spec there that I care about far more than the others is RAM. I often have hundreds of tabs open in several different windows. I'm organised, but this is simply just how my mind functions best. In any case, I need 16gb RAM. I have a 3-year accidental warranty due up in August of this year. Prior to it expiring, my current rMBP will likely mysteriously 'break'. I am presently deciding what to replace it with. My options are a new, maxed-out 15" rMBP (basically, the same thing I have now, except with three years-worth of cumulative slight performance bumps), or that new 12" rMB. And I soooooooooo want that new 12" rMB. Unfortunately, as you likely know, the max RAM on the brand-new 12" is 8gb. After a lot of thought, I've decided that I could live with 8gb of RAM, in exchange for the other new features/battery life/lightness, but if and only if the next year's performance bump (and the year after, and the year after) of the same 12" model will not have an optional 16gb. (Basically, I'm trying to avoid telling myself 'I told you so' in a year's time.) So here's my question: Is it a physical possibility, given the internal design of the brand-new 12" rMB, that 16gb could potentially be had? Like I said, I know very little about hardware, but that which I know about RAM is that, in the case of the rMP/rMBP, it's soldered in (so that it's non-replaceable/non-upgradeable), and that it occupies physical RAM slots. So, if I understand my own question correctly, I'm basically asking a) Is there another empty RAM slot so that next year Apple can stick in another 8gb and have 16gb RAM total, or if not, b) Can next year they simply just stick in a single 16gb RAM card instead of an 8gb (so, basically, do they even make single 16gb RAM cards)? Thanks much.
