Lenovo offered the good display (2560x1440 HiDPI) only for some weeks in autumn last year.
I want to buy an X13 but with the available standard resolution displays it doesn't make sense. I don't know what drives Lenovos decision here because the RDNA2 has a lot of power and would be a perfect fit.
A quite capable AMD-powered model variant of the ThinkPad X13 Gen 3, which comes with a spacious 1TB SSD and the brightest display that this series has to offer, can now be purchased with a significant discount thanks to an offer from Lenovo's official sellers account on eBay.
