Also, there is supposedly a BUSINESS option with Windows 10 "PRO" with Core i5-8350U quad-core. The 8350U would be the MUCH better choice than the the 8250U as it benchmarks are on par almost with the i7 8650U. So if your looking for better CPU performance and possibly better battery life and a lot less money than a i7, then the i5-8350 may be for you. But might as well get a i7 8650U if you need a bit more cpu power than the typical Office suite only user. I.e. graphics such as Adobe Photoshop, Illustrator, CorelDraw etc. The integrated 620 gpu won't get you blazing fast update rates with 3d software such as 3dsmax, maya, fusion 360, solidworks, etc, but it may get you by in a pinch or for simpler work since no discrete gpu such as gtx 1050, 1060, 1070 etc. You'd need Surface Book 2 for that. (Or wait for newer models).
Overall, the better the cpu, the better off you'll be even with substandard 620 iGPU if not your daily driver.
