They will have to drop support for any newer system type because the W7 OS was not originally designed with those systems in mind, therefore the cost in time and wages would offer zero sum return and actually degrade performance for older systems. So, yeah, totally understandable.
@bustr: the MB that Boilerdown linked to includes an M.2 NVMe socket that they report can hit 32Gb/s, which means you have a lot of options for a speedy/snappy system. I haven't tried one, because I lean toward the WS side of MBs, but it is popular for a reason.
@715: MS is at least aware of the complaints involving privacy. For the second time this summer I had to re-activate W10, and both times the support personnel went out of their way to tell me that they would not be looking at my personal files (d*** right, I reset the OS beforehand anyway so there was nothing to see), but the idea that they do not have the automated activation system of the past is curious at the very least. W10A Pro does have a lot of additional functions above and beyond what W7 ever had, but not anything W7 cannot have if wanted. Still, W7 no matter what you think of it is going to begin to lose ground from here on out.
