4700U for £899 with 16GB is actually pretty nice, there has also been sparodic 4700U availability over the last couple of months of the Ideapad 5 (8GB only though) but both the Yoga6 and Ideapad5 suffer the classic issues I'm complaining about. One isn't available for another month, despite the CPU being launched 12 months ago, the other is suffering from patchy availability in anything other than the low-end 4500U variant. Both are cheap, plastic laptops with flexy keyboard decks, mushy typing, and poor cooling, and both come with mediocre low-gamut, standard-resolution, 60Hz, no VRR screens which, although serviceable, are distinctly non-premium, bottom-rung solutions.
My personal (and corporate) experience with Lenovo is that if they have a shipping date of more than one week, you'll be waiting for a couple of months before they cancel the order and tell you that the model you ordered is unavailable.
I've been buying laptops for myself and others for the better part of 20 years. Renoir availability is an outlier that sticks out like a sore thumb, and COVID isn't to blame because Intel 8th/9th/10th/11th gen have remained in good supply throughout the pandemic, even if stocks were low and I ended up buying a different model to the one I initially wanted. I can still buy Ryzen 3500/3700U models without any difficulties, too.
This article is about AMD losing market share to Intel, and as much as I want AMD to be available, successful, and providing meaningful competition that benefits us as consumers, I'm not seeing it happening. The difficulties I've had sourcing Renoir laptops for the last year and the loss or retraction of design wins from OEMs over Q1-Q2 2020 have been eye-opening.
