I was using a ~2011 x220 as my personal laptop until 2021 or so, when I replaced it with an X1 carbon. This lasted almost 2 years until it stopped charging, and Lenovo wanted more than the laptop was worth to repair it.

I've since switched back to the x220. Whilst I miss the extra memory and CPU grunt, it gets the job done. When this one finally dies I'm not sure what will replace it, but it certainly won't be another Lenovo.
