For what we do I’ll never understand spending 1500-3000 on a laptop. It’s insane given the environments we work in. On the other hand, a RJ45 Jack is imperative to me. I don’t want to carry around a dongle and be on the 3rd floor and it be down in the work bag. I think you guys probably don’t realize how much we actually use one.
Before I moved to Mac, I was buying $500 ish laptops every 3-4 years and having to "refresh" them at least once a year. I bought my current Mac Book Pro in 2011 and it still works great to this day. It is definitely worth investing if it will last. Your laptop is a tool. How many times do you replace your drill?
