For the last few years, it was starting to look as though Microsoft had run out of ideas on how to actually improve the Surface Pro line, beyond tinkering around with the interior. My 2015 Surface Pro 4 looked functionally identical to the 2019 Surface Pro 7, complete with ultra-thick bezels around the screen. Though we were all excited when the Surface Pro X came out three years ago, its flashy new design concealed a fatal flaw: running on an ARM processor rather than Intel made it struggle to deal with common applications.
