I have an IT consulting business and in the past year I find I am on a laptop working on-site 50+ hours a week. My vision checks out ok but I am having a lot of trouble with eyestrain. I am looking at 1080p 17"+ laptops with IPS screens. Software I regularly use does not support scaling, so 3k/4k seems pointless to me. Battery life used to be important, but now I am plugged in 90% of the time. I do regularly use photoshop/illustrator but GPU performance does not seem to be an issue. The Intel integrated in my current Lenovo T560 is fine in this regard. Reliability is a big concern. If I miss a day due to laptop downtime it is a problem. What are my options? Looking at the Lenovo P71 right now. Only downside for my application seems to be the 9 lb weight.
