Bought an X220 years back and it unintentionally became my main laptop for a few years. Sold it on in much worse condition (I kept the keyboard) at a profit and got an i7 X230T instead, which has also somehow gone up in price since.

the X230 didn't last as long, the efficiencies of the M1 macbooks were too good to ignore. Gave it to my mother since because she wanted "an old laptop that just works"
