My wife needed a new laptop just recently and she's a ThinkPad-only kind of gal. It was nice to see that there are many AMD options, but you can't buy them. In fact, you can't buy much of anything from Lenovo. Outside of the L13 (what she ended up with), everything is "ships in 5+ weeks" on the Lenovo site.
Having one in stock at NewEgg or Amazon might be helpful, but they are typically base spec with soldered memory. If you want 16G+ memory, you are just generally out of luck.
Look for the Asus TUF 506 and Asus Zephyrus G15.
