1. The Type-C charger should accept higher voltage from PD or QC for faster charging and more running power.
   
2. Barrel jack is not needed at all, I don't use it because almost everything else I have uses USB charging.
   
3. The headphone jack I am not sure about, currently I have it switched to serial mode and I never need headphones, and if I do I can use a dongle or Bluetooth. But if the switch would be more accessible, then sure I wouldn't mind it.
   
4. The other privacy switches should also be physical, I have never used the keyboard controlled switches. Something line the PinePhone, I mean.
   
5. The USB system itself has some PWM whine when you plug in devices or cables.
   
6. The speakers have similar noise when playing audio, also pops when audio starts playing.
   
7. The speakers have reverse polarity, so "Invert R" or "L" has to be selected in alsamixer always but switched off when plugging in headphones. (You may not notice this because distros include a script to do it automatically)
   
8. The speakers should be flipped to fire upwards, also maybe better speakers as well or better EQ.
   
9. Power key should be moved to a button off the keyboard, the key should become the Delete key. Or maybe Fn+F10 or something like the Pi400.
   
10. Rubber adhesive feet tend to come loose. I have a roll of double-sided tape in my laptop bag to stick them on but it's ridiculous to have to be so careful to not move the computer on a desk too hard.
    
11. WiFi signal is too weak, is it the antenna or the adapter, but it is in some situations unusable and I have to tether to my phone or something.
    
12. Would be nice to get the unused USB 2.0 ports available either inside the case or outside.
    
13. Cooling solution could be improved, I think the thermal interface between the case and the SoC could be a bigger heatsink rather than the heat conducting pad that it currently uses, also the power chip needs cooling especially if higher power is available from USB.
    
14. I don't think a fan is necessary, it's possible to use one of those laptop coolers or I have used also those cold packs for sore joints that go in the freezer (don't recall what they are actually called).
    
15. The screen could open a bit more and the case in general could be a bit more solid, but I do like how light it is currently.
    
16. Charging led is hard to see, have to used the my finger to reflect the light. Would be nice to see the charging led next the the power led on the top, and also duplicate power led on the side so you can see if the laptop is turned on with the case closed.

I've had possibly just one barrel jack fail from extreme abuse in five decades. The only way to convince me to get rid of it would be to replace it with that new Apple connector or something like it. It is mechanically superior to small USB connectors, vastly so.

Those arguments for USB-C remind me of the same arguments for mini USB-B. Everything I had, had those at one time. Now they are a nuisance. Still, a cheap USB cable isn't much use when the fragile port is broken.

If you don't like your barrel jack, fill it in with epoxy.  I guess I can still install one when it's gone.  Wouldn't be the first time.
