Say what you will about Apple, I think they lost some originality when they ditched PowerPC back in the day. So I'm happy to see them doing something a little out of the box, even if it is just kinda tapping into the design chops of their mobile teams. ARM is very common these days but not in machines intended to replace rather than supplant current PCs. It makes me very excited to see what someone like Qualcomm could make in the same category, if they could also have some sort of x86 translation acceleration ASIC for some hypothetical JIT emulation under Linux or Windows. The Surface RT may have died in vain but it might just be time to see what such a thing could look like some ten years down the line with better engineering and planning.
16GB is awful sparse for a machine somewhat intended for content creation and creative types in general, yeah? I remember when Apple machines could take nutso amounts of RAM for the day -- the PowerMac G5 tops out at 16GB itself, I believe. Now in the day of soldered memory, I'm bummed to see them topping out at that, still. 16GB is still generally what's recommended for a gaming/general use machine today, and I don't doubt macOS still holds some claim to being lighter on memory than Windows [citation needed] but for that to be the maximum? Ouch. I hope their Pro offering doesn't suffer from the same issue.
