Finally replaced my 10-yr-old laptop, as it was slowing to a halt, and the messages I got when browsing changed from "Some functionality of this website may not work with your browser version" to "What the hell is this operating system, Dude, Windows 3.1!!?" After looking at reviews of mid range models I chose a Lenovo Ideapad 15.6" screen with an AMD Ryzen CPU, which scored well on performance.
Big mistake. Worst screen I've ever seen - poor contrast (no black, just muddy dark greys), inaccurate, low-saturation colours (which no amount of altering colour calibration helps). It makes my old laptop (which was a budget model itself) look like a high-end Apple by comparison.
Just thought I'd mention it if anyone else is buying a Windows laptop. It may be good performance, but if visuals are important, forget it!
