Thanks for advice! Now, I still use the best TabletPC ever build, the Surface Book 3 - the 15'' display alone combined with the pen is the most advanced device so far and not too heavy for holding it. Unfortunately, since there isn't an ARM processor inside and now getting older, the build-in accu is getting empty pretty quick. That shouldn't be an issue with the new processor. I don't understand, why Microsoft doesn't has a successor in the pipeline; don't they - and JRiver . want make money?!
