I can't totally disagree. I could have gotten a device at 1/2 the cost that would have performed about as well (and not had that display driver glitch).
But:
1) My last laptop lasted 9 years. I plan to ring every bit of life out of this guy that I can. So in dollars per year, it shouldn't be to bad. About one beer a week I figure....
2) There is NOT anything on the market quite like it and it fits my needs. Trust me. I had looked for
months at various devices to fit my needs. The closest I could find to what I wanted was the HP Spectre X360. And that screen was a touch small for my needs. (The 3:2 on the Book is about perfect for me)
3) Yes, I do believe Microsoft has the cost a bit higher then needed on the entire Surface line. Part of this might be to keep the other manufacturers from getting too upset with MS for getting into their market space. There are things about the Book that nobody else quit does. Maybe that will prod them to make more premium products. That is often brought up by reviewers and owners, when comparing an Apple product to some other manufacturer. The Apple users often buy Apple because it has a 'premium' feel. Nothing wrong with MS trying for that space.
4) Yes, there is a bit of ego, or whatever you might want to call it, involved. Just an hour ago a few of us were standing around my Book, and a friends budget priced HP 2 in 1. His HP worked just fine of course,. Though I was showing him around Win 10 and noticed right away that there was some annoying lag and delay in doing things. But everyone stared at the beautiful saturated colors on my Book screen. And no, I don't have a BMW.
