A small number of components (the curved edge just above the keyboard, for instance, or the roller handle) seemed purpose-made for this model, but, like 99% of the pieces were totally generic. And this is in a set with more than 2000 pieces with lots of very intricate mechanics (there's a roller, a carriage, air pistons, and a ratchet/escapement mechanism that moves the carriage), but virtually all of it was made up of standard bricks, rods, connectors and generic components. I was super impressed. Even the keys are just Lego disks with stickers on them. The spacebar is just regular Lego with a smooth surface.
I feel like people have been making this complaint against Lego forever, and it's always "when I was kid, we just got a box of bricks and let our creativity take over!". The harsh truth is that Lego didn't change. We just grew up.
