It’s pretty tight in there, for sure.
The quips about the design also make for entertaining reading, but the bottom line is that, as expected, there is virtually no hope of this model ever being upgradable after it leaves the factory - which, incidentally, also lowers its resell value.
So if you get one, pony up for the 16GB in advance - and maybe a CPU upgrade, too.
(Me, I’m still waiting for any hints regarding the future of the desktop line to make up my mind - that’s my biggest concern right now…)
