Cracked MacBook Pro screen, repair or replace?

Which one is it, Intel or M1? That decides it. Apple's out of warranty display repair on a 13 inch Pro has tended to land somewhere in the 400 to 700 dollar range depending on model, and independent repair shops usually come in under that. If it's an M1 era machine I'd fix it, they're still quick and worth more than the repair. If it's a four year old Intel one, price the repair against a used M1 Air first. Don't sit on it for months though, those lines spreading from the crack keep spreading. Back up now and use it on an external monitor in the meantime.
