Lenovo’s choices with U vs. P variants are confusing sometimes. For example, why on earth would you try to cram a hot power hungry P-series CPU into the X1 Nano, a machine with tight size/weight constraints reducing cooling and battery capacity, like they do? Everything about that model screams U series but you can’t build one with that config.
