I'm not sure why anybody would need 64 gb RAM in a notebook.
I, and others in my field (music composition, full orchestral scores) need as much ram as we can get.
16gb max?? What year is it?? Laughable, the absolute minimum ram they can put in (that I can reasonably justify spending the kind of money they will undoubtedly be asking for) is 32 GB. I'm hoping for 64, which would allow me to mostly replace a desktop (but I could easily use 128 if they gave it to me). That's just for my virtual instruments + plug ins. Then if you add in Virtual Machines for various purposes it gets expensive fast. 64GB was available in other laptops out last year (example: thinkpad P90).
I'm not alone either, there's a lot of us (other fields besides music composition) that need MOAR! RAM for heavy work. Yeah I know, most of you don't need this, and for some reason people think the laptops are too thick / heavy? WTF? Eat a meal, and use your arms occasionally sheesh. As time moves on the trend is always to use greater amounts of resources anyway, and this will hopefully be my main machine for years to come. Here would be a good place to quote the classic Bill Gates line about no-one ever needing more than 64k ram ever. Yeah, how did that work out? Heh
Frankly, if the ram was still user replaceable in the current 2015 model I probably would've bought one already and then later just do an aftermarket upgrade on the ram down the road when someone undoubtedly would make chips of greater capacity but that ship has sailed.
And yeah I realize Apple doesn't care about me or my kind anymore, I realize everybody in Cupertino appears to be drunk on the mountain of profits from i-stuff and has seemingly forgotten all of us, but they have people like me (and most of you in this thread) over a barrel because just look at our options: Windows? **** that, ChromeOS? Might as well go iPad pro then, Linux? A pain in the ass, (but honestly looking more and more like the way to go if apple can't throw us a bone).
That leaves apple, and what are the choices there? A Mac Pro? Yeah go view the trail of dead and the oceans of salty tears in that forum if you aren't well aware already.. iMac? I guess, but if I'm buying non-upgradable laptop parts anyway, why not get the portability too? Mac Mini? Gimped, and likely dead anyway. That leaves the MacBook Pro and for ****s sake, here I am 3 years later with all you other poor bastards (I love you!) still waiting for skylake with the possibility it won't even be released or available this year.
AAAAAAAAAAAAAAAAAAHHHHHHHHHHH!!!!
