PSA: there's a protective sticker on the trackpad
This may very well be common knowledge, but a comment in another thread from u/theflippantsouvenir just saved my trackpad experience.
Basically if you haven't removed the protective plastic sticker, the trackpad will feel sticky, be less responsive, and be all round horrible to use.
The sticker is transparent with no visible tab, so it's actually extremely hard to see, and I was initially worried that I was peeling away some integral part of the trackpad, but once it's off the difference is night and day.
I feel very silly!
