Believe it or not, the worst device for repairability is actually the Windows Surface laptop. If you need anything repaired on it you basically have to send it back to Microsoft. It was rated the worst to repair by several different tech sites.
I got one of our employees a Surface Book 2 when it came out. It worked great until last month when one of the heatsink's fan started to die. Because it was one of those detachable ones, replacing that fan involved putting the top portion of the laptop in the oven to loosen that sealant they use around the screen.....I ended up just purchasing him a new laptop instead.
