It started literally falling apart in 6 months. One of the usb ports stopped working, the disc tray was stuck, the bottom left of the trackpad was sunken in, and the whole laptop felt cheap and was plastic. A ton of flex in the whole thing.
The worst experience I had with an aluminum mac was dropping it while open and having the screen shatter.
It's a shame that IBM sold its PC business to Lenovo. Maybe it's just the model I have, but Lenovo's ThinkPads feel so much worse in quality than IBM's ThinkPads. I probably won't get another one when the time comes to replace mine.
That said, I'll consider a Framework or Starbook next time because even T series Thinkpads are getting thinner and bendier and the keyboards lower and worse.
There's a bunch of other series that are newer, consumer-oriented and do not share the body or traits that the Thinkpad series is reputable for.
That said, if I was in the market for a laptop today, I'd look at Framework.
An x395 bought in 2019 is my daily driver. It's as new.
The M2 Air is astonishingly light, while being made of metal, as opposed to the ThinkPad's (cheap imo, but subject to debate) plastic. Don't see what the argument is.
My point isn't that Airs are bad, but that they're not ideal for some tasks and saying any machine is "the best" without mentioning what you're using it for is less useful of a statement than you might think it is.
Thinkpads basically look the same for 10+ years.
