Not gonna lie. Love me some ThinkPads too.
Just for their keyboard though. Which is second to none. All metal casing is nice too.
Build quality is alright, but it is a far cry from the old T410s days where they were a fucking durable tank. Back then you could chuck it across the room like a frisby and it be perfectly fine. Now even for self repair and upgrades. The modern ThinkPads are more finicky and fragile once you open them up. I feel like an old fart saying they dont build them like they used to.
Stay the fuck away from Apple hardware. Sure they are excellent build quality. However as someone who worked in a certified apple repair store. Seeing the capabilities Apple has behind the scenes to remotely fuck with your hardware. Even with Linux on it. Im just going to say a fuckedity nope nope.
Even though many people never experience any problems whatsoever when they convert mac hardware to Linux. I am just a little too skeptical, paranoid, and overly cautious. Especially when it comes to owning anything that Apple makes in the first place.
