"4k isn't for couch potatoes", "you should buy a $500 monitor", "if you are programming on something so old, [you suck]", etc...
I am fairly surprised to see this style of wording upvoted to the top of HN, actually.
But yes, it's opinionated. I'm quite strongly of the opinion that in general larger desktop displays increase productivity. They are finally arriving, and at prices that are almost affordable. With several important caveats and weaknesses that cannot be ignored, the market is finally moving in a direction that I applaud. So this blog entry/rant is a form of celebration.
There is a time and place for everything.
I am not criticizing your writing style. I just found it odd to find one like it at the top of HN is all.
I actually like it. It reminds me of kenrockwell.com
