The surface line up (the tablets I mean, the actual "surface", not the laptops that share the brand) have been craving for a solution of this type, the current (and previous) Intel iterations really do the name and form factor a disservice.
Since you mentioned the 2P+8E what do you think about them and the rest of the Intel line up with 4p/6p+8E (28w p-series) and 6p+8E ("45"w h-series)?
My only experience with them is with LG Gram laptops. The 2P+8E i3-1220P is amazing for the typical non-multitasking jobs you need an ultraportable for and the "TDP" never feeling slow or underpowered, and never getting hot or nuking the battery runtimes.
I've not dealt with mobile versions of Alder Lake outside of those LG Grams, simply because AMD laptops have considerably longer battery life outside of the Intel-only limitations of "it has to be an LG Gram".
If I'm buying laptops, it's usually ultraportables where battery life, performance/Watt, and IGP driver compatibility with CAD software matter immensely. Zen3/TSMC 6nm runs circles around Alder Lake/Intel
10nm7nm and the Xe graphics drivers present numerous issues where the AMD graphics drivers do not.
