That's true but at least the HP machines use parts that can readily be handled by actual human hands. I had an iPhone apart for a repair earlier today where one cover (over some connectors to keep them in-place) has 4 screws, one on each corner, all of different length, the longest being 2mm and the shortest 0.3mm. That's ridiculous!
