The HP Dev One follows the HP EliteBook's poor design of pairing the pointing stick with 2 mouse buttons instead of 3. Without the middle mouse button, you can't scroll with the pointing stick and you'll need to use the trackpad (or apply some hack to the 2 available buttons), which makes the pointing stick a less effective tool.
I've tried that, and it was so uncomfortable to hold down both mouse buttons with one thumb that I did not find this workaround worthwhile. It was awkward using both thumbs to do the same.
The Elitebook model that the Dev One is based off of has a SureView screen, which is what the Dev One ships with. That's to say it is an intentional privacy filter. I didn't find it to be washed out and the gloss is comparable to a MBP from a few years ago.
ThinkPads are still popular, so I don't see this as a joke. A pointing stick (TrackPoint) is excellent for people who want to use both the keyboard and the mouse while moving their hands as little as possible.
Unfortunately, the StarFighter has soldered memory, which is one of the main drawbacks of new ThinkPad models. Star Labs also sells the mid-range StarBook laptop with replaceable memory and the low-end StarLite laptop with soldered memory. On the other hand, Star Labs is Linux-first and pays the developers of the pre-installed Linux distribution configured in the order, which is an advantage over Lenovo for Linux users.
