But is it a normal Windows PC that supports normal Windows software or the weird abomination they had last time that supported a few specific apps and nothing else?
It's normal Windows, just on ARM. Windows on ARM already supports x32 and x64 emulation. Pretty much the only stuff that doesn't work is hardware drivers (to be expected) and games with kernel level anti-cheat (also expected). They've also announced a new 20% faster x64 emulation layer. Recently there's been a big push of apps getting native ARM ports too, Chrome for example.
For the last 5 years starting with Windows 10 (Snapdragon 835 based devices) you could run any x86 software (that doesn't require driver/drm rootkit) and 64bit emulation was added with Windows 11 (when intel patents ended).
Sometimes it feels like the commenters on HN are being kept in suspended animation for 10 years then revived for a couple of days to comment then put back to sleep.
