The 6950 XT is faster than the 3080 except (usually) with hardware RT enabled, not slower. The extra vram is also a significant advantage, though that will probably become more relevant over the next few years, and isn't a significant advantage yet except in some fairly rare situations.

It's not always well suited to doing 4k without upscaling, or without turning down some settings.
That being said, FSR upscaling works particularly well at 4k, and is very much worth using at that resolution, and the 6950 XT is particularly well suited to that. An RTX 4070, 4070 ti, 3080, 3080 ti (etc.) by contrast, is a lot more likely to have issues running at an (internal) resolution between 1440p and 2160p, because of having only 10 or 12GB of vram, especially with more demanding games released over the next few years.
Better value, or better overall design? I can see the value argument, but if you don't mind paying more, I can see why someone would think that this Legion Go is better. In what ways do you think the Steam Deck is better, and in what ways would the Legion Go be better if it were more like the Steam Deck?
My mom's computer skills were bad, and in decline because of her cognitive decline, and I switched her from Windows to Ubuntu around 6 years ago because it was actually easier for her to use, even back then, and it's improved since then.
I generally think it's a good sign when something is heavy relative to its size.
I just saw a different review of this and it definitely looks very good.
Are you sure that you wouldn't rather just get a good air cooler?
Pumps eventually fail, and the 13700k doesn't need an AIO. A good air cooler could potentially last many decades, though you would eventually need to replace the fans (and, thankfully that's very easy to do). The trend in motherboard design is to make them compatible with previous generation coolers (AMD did this with their AM5 platform, and even a lot of AM3 coolers were easily convertable to be compatible with AM4 and AM5 systems).
I've been using the same air cooler (a Noctua NH-L12) for about 9 years, first on an AM3 system, and currently on an AM4 system. The fans still sound as quiet as when I first got it. The quality of this thing is amazing.
