USB-C power delivery standards only go up to 100W - that's why the power supply can't deliver more than this over USB-C. Dell cannot fix this while remaining compatible with the standard.
If they would cook their own proprietary extension of the standard, it will only work with the Dell power supply (and cable), which loses them one of the key advantages of having USB-C in the first place - a single cable that delivers power and docking connectors.
So I don't expect there will be a "fix" for this. It's just something to consider before purchase.
Apart from that, I agree with most of the review. The display is the key selling point here, although I wish there would be a non-glossy, non-touch option for the UHD+ display. I loathe gloss and don't need touch. But there is hardly anyone else doing 16:10 displays yet.
Only Microsoft's Surface does good displays in non-Netflix aspect ratios, but their hardware is all glued together with zero expansion or repair options. This one at least has sockets and can be opened, although it sounds like it's still a bit annoying to do.
I would've liked some more connectors too, especially since USB has a sad history of never quite working right. No idea why the "Killer" brand Wifi is such a thing these days, Intel must be heavily discounting this nonsense for OEMs.
I also don't find temperatures well over 40 degrees near the keyboard acceptable - it's painful to touch!
And of course there's no trackpoint :-(
