As someone who used the X220 for quite a long time I can agree. - The chassis has a bunch of weak points so build quality is not overall excellent and that shows after some time. Especially bad is that part above the screen where the antennas are mounted inside. It's made out of plastic and is only flimsily connected to the magnesium back panel at either side, if it breaks you have to replace that whole back panel. - That Sandy Bridge CPU turned out to be an exceptionally future proof choice but after >10 years it shows its age. Even if it's fast enough for your use case, modern CPUs are just much more power efficient. - USB 2.0 only, except on the i7 motherboard, not the most popular configuration so harder to source for a good price. Alternatively an express card can be used but did not have that good of an experience with those, also the mounting mechanism on the X220 is not sturdy enough. - Good luck finding a proper battery pack nowadays. Even if you still find an original one, after years in storage they tend to loose capacity quite fast. Most third party ones are garbage from day one.
