Yeah, I've been keeping an eye on USB4 and WiFi 6E - and avoiding new devices for the time being - for this exact reason. My dream setup involves a litany of dumb displays in different form factors - VR, tablet, desktop, or whatever else - that I can power from one primary device, rather than buying a slew of discrete systems that'll be compromised on spec in order to accommodate larger screens etc. [1] But the I/O for that won't quite be there until sometime next year.
Add to the mix GKIs; AOSP's recent ability to boot from mainline; and the ensuing implication that all of these new adaptive shells being developed rn for the PinePhone could be reused on an Android device [2]; and the thought of 2021 has me salivating.
[1] Mostly, anyway. Some stuff would still be purpose-built, but realistically the main limiting factor for my phone as a daily driver at this point is the form factor.
[2] Assuming bootloader unlock, at least until we see how DSUs play out.
