While I adore my lenovo x220s (plural), I finally stopped using them and bought a 3rd hand (correct) lenovo convertible. There is one key reason: battery. Yeah, they're quite cheap, though not as cheap as the author claims (around 25 - 35 EUR mark, and only that cheap if you buy off aliexpress), but they're all (ALL) - s***. I've bought about 4 in total, various brands, including those with glowing reviews, and they were all s***, regardless of their claims. They last 2hrs, if I was lucky, AND wear out to very low capacity after a few weeks' use, so near-instant landfill. I can't spend the rest of my life hunting for a 'good enough' battery, so I retired my lenovos, even though the swappable battery and hdd, and fantastic keyboard beats the s*** out of my 'current' model (which is already considered 'ancient' being made in 2018 and each and every newer version is worse in every possible aspect).
