Lenovo had quite a few clearance sales in the past, but the one that is supposed to end in less than seven hours looks like the best one of the year: two ThinkPad X1 Yoga Gen 4 models and a ThinkPad X390 Yoga, all with price cuts of over 60 percent. All come with Windows 10 Pro 64-bit and 512 GB PCIe SSD storage.

What's truly shocking is the original price. Ancient Skylake and meager 8GB LPDDR3 for over $2800!!! This is essentially the same thing as a ~2016 flagship, except the 8GB RAM was no longer the top option even back then and the SSD may yet be slower because the early MLC were really fast while this likely carries cheap TLC.
