I am excited over seeing this project, but these things have stuck out for me:
1. I am concerned over long-term screen hinge strength. I can't see the build on it, but I will not cheap out on that after dealing with bad hinges (screwed into plastic, not a metal frame on a Dell)
2. I am concerned over the durability of the screen. I am not an expert at this, but I have no worry over the screen if I chuck it in a bag or my cats who sometimes stand on the top of the laptop when I put it on the floor.
3. I watched Louis Rossmann's takes on it - I was hoping he would go into the tactile feel of the keyboard. I can wait though for any commentary on that from a ThinkPad user. I can try to stop using the TrackPoint (would hate unlearning that) but a good laptop keyboard is essential. (I declare the best laptop keyboard I ever experienced is the one I have on my t430s. Lenovo has made the key travel lower and lower over the years. The t470p and others around that year I used is OK, but doesn't compare really.)
If anything were to go wrong though, hey, I can at least repair it :D But, I continue to stare in wonder over this. I'd love to be proven otherwise on these points.
