Also, for those making a $2k+ purchasing decision, it pays to do a little research as to what other people who work in similar situations think about the different options.
I read a lot of reviews for MacBooks, Lenovo T4xx series, Dell XPS models, etc. Just like with any other topic, the color of varied opinions helps one arrive at a better understanding.

Since my comment is abrasive -- much more so than normal for me here on HN -- I figured it was worth it for me to put some more effort into this and provide some evidence. I easily came up with the following list of topics here from the last month:

I just stopped after this point. There were more.
Thankfully there is a lot of positivity, though you have to look harder for it.
Imagine being on a Muscle Car Enthusiast forum, and Ford released a V8 Mustang that had less horsepower than it's predecessor, and worse handling, but just came with minor stylistic upgrades. The same thing would be happening.
For the rest of us, it is an equipment choice that might have to make at some point, and the we'll go back to work on our code ;).
