The Thinkpad series is performance oriented and business grade.
The Ideapad series is performance and price point oriented and consumer grade.
The most expensive off the shelf Ideapad on the lenovo website is cheaper than the cheapest Thinkpad x-series. You bought a cheaper laptop, and it wasn't as durable as a series of laptops that is advertised as more durable. I'm not sure that we are regressing in this case.
Buy a modern equivalent to your Thinkpad x220t like another Thinkpad x-series if you want x-series durability.
