Pricing has always been funny with these NUCs!
They've always started selling what is essentially a notebook without all the notebook parts for a 'premium' over an ultrabook, ...which seems like they tried to take another page from a fruity cult script.
So I shied away very far and would have never looked again, if I hadn't been desperate for something a bit more powerful than my Atom Mini-ITX boards and could only find some NUCs, which all of a sudden had reasonable prices (50-30% original list) towards their EOL.
And that's where I've bought them since and got some pretty decent hardware, too. The Enthusiast models with dGPUs were a real steal sometimes, where you'd get the (mobile) dGPU at near zero extra cost!
Intel evidently could afford for quite a while to overproduce and then eventually empty stock at prices that then were essentially a notebook minus the mobility parts, but I'm less hopeful that Asus will do the same.
So perhaps it's the end of the road of NUCs as a special value proposition for me.
But these days there are Chinese companies like Erying quite ready to take surplus mobile parts and selling them at far more modest profits, but without BIOS updates or any other type of support.
