I admit that I’m extremely interested in how this pans out, especially if the devices end up getting solid Linux support. I wish it had upgradable LPCAMM though.
You gotta give them props for this go around on everything else, the LPCAMM spec may have been ratified too late in the board design and prototyping phase. That or they reaaally didn't wanna give up the extreme RAM bandwidth they achieved here.
Surface devices in the past have also been very Linux unfriendly, necessitating entire online communities dedicated to even attempting to iron out the bugs. So despite the recent announcement for the processor support in the Linux kernel, I'd say temper your expectations for a Microsoft device.
But if they do deliver a mostly modular, mostly repairable, mostly Linux capable Surface series, and stable x86 emulation in Windows, I will standardize on this equipment in any future IT fleet. There will always be needs for specialty hardware depending on the person, but a snappy all rounder for the rank and file is my biggest desire up front, because RISC will win in the long run, but it has to get adoption started somehow.
