I have an old RK3399-based Chromebook. I now end up using its Intel "Core m"-based counterpart (originally bought for my partner) more, but the ARM machine was/is 100% fine as a fancy terminal for my backend Web dev work. I had no trouble messing with Go on an even earlier ARM (Tegra K1) Chromebook. The Surface Pro X did not take off, but I suspect that's a combination of ARM not being competitive at the high end and needing a friendlier ecosystem. ARM might do a bit better once larger core designs and denser process nodes (RK3399 is 28nm!) filter down to lower-priced devices and there's great software to run, like a refined Windows/ARM or Chrome OS w/Android or something else. (I've been hoping for ARM to make inroads into Serious Computers for some time, so who knows, but it does seem successful in lower-end Chromebooks, and Amazon and MS are publicly experimenting with it, so...)
