Can't say I am not surprised. Intel still has the market (and mind) share in laptops and vendors like Dell know not to anger the company that feeds them. It seems AMD based laptops will remain 2nd class as long as the big players favour Intel. There are heaps of articles regarding Intel's past behaviour and how they coerced resellers (Dell, HP, etc) in not producing AMD based systems or ensuring they were substandard. Just google it and you will find the articles.
We (my work) looked at some Lenovo AMD based laptops, but were shocked to see Lenovo were only using single channel memory which can really hurt Ryzen CPUs. Not to mention the RAM was surface mounted, so no upgradability. The demo unit SSD was also much slower than it's counterpart in the Intel equivalent laptop, so overall the AMD based laptop was noticeably slower.

The only laptop producer I see at the moment that seems to be offering an non nobbled AMD based laptop is Framework. Not sure when their release date is on it yet. One to watch out for.
