I’m own a FW13 and I have bought ~4 for employees.
I doubt I will order more. We’ve had small and large issues.
My Linux machine will drain the battery completely if you don’t perform a full shutdown, and even then the quiescent drain is too high and I can expect it to be dead in a week.
The dream of repairability is great, but the reality just isn’t there.
That said, I was able to replace a damaged screen with no effort at all. A far cry from the MS Surface I had previously, but any vendor could sell a screen or keyboard without the “full modularity” that FW pushes.
