Anandtech posted a review on the Microsoft Surface Pro 6
A quote from the article:
Microsoft is in a bit of a unique place in the PC space compared to other manufacturers. Other than Apple, Microsoft is the only company that controls both the hardware and software sides, and when the Surface lineup launched way back in 2012, Microsoft’s goal was to showcase the advantages of their platform with a premium hardware lineup. On October 2nd 2018, the company unveiled their sixth iteration of what is now a staple in the PC space, the Surface Pro 6.Microsoft Surface Pro 6 Review
On the outside, it would be easy to write this refresh off as a spec bump, but there are tangible improvements throughout the Surface Pro which make this a worthwhile successor to the 2017 Surface Pro. The company hasn’t completely reinvented Surface Pro since the Surface Pro 3 launched in 2014, with the move to the new thin and light form factor, showcasing the 3:2 aspect ratio display. Surface Pro 4 stretched the display from 12-inches to 12.3-inches in the same size device, and moved from Haswell to Skylake, and Surface Pro 2017 made some more small tweaks, and with the move to Kaby Lake finally solved the power management issues that plagued the Skylake generation of Surface devices.
