UPDATE: in the two days this was up, having combed through the comments on three separate occasions – the following seems to be the general consensus, in rough order of relative importance:
1. S3 standby/sleep support required
2. low weight for luggability, 2.5lb maximum
3. survives table-to-floor falls
4. always-on-AC battery deaths unacceptible
5. survives being in a bag, accidental activation
6. Linux support for all hardware
7. trackpads on par with Apple, at least
8. keyboards with clear actuation, spill resistance and backlighting
9. kill switches or modular hardware for camera and mic
10. bright matte screens, with vertical space
11. memory and I/O performance approaching Apple's M1 SoC
12. HDMI, USB-A, 3.5mm, 10gbE, SD, USB-C periferals are what people own, support that
13. trackpoints are great for text-editing
14. quiet operation, no blinken-lights
15. prefer no webcam over shitty webcam, no BT/WiFi over shitty BT/WiFi
After the Apple event streams I shall post a list of laptops people seem to have a history of enjoying.
I would use the laptop for rendering and modelling, animating and music production, video encoding and massive compiling. Maybe a few virtual machines. If it can handle it.
EDIT: of course a lot of reading, coding and writing.
Thanks everyone for participating in this discussion, I appreciate you all.
