Bring back the accessories.
Honestly ASUS really messed up there. I get that the accessories didn't sell well but it's because the marketing was just abysmal.
I saw some reviewers mention the twinview dock for instance, I thought, well thats gimmicky, 2nd screen, will drain battery and then its so pricey, won't buy.
Then I took a better look at years later and realized, that thing has some amazing features. Built in cooling, 5000mah battery, actual shoulder buttons, additional speakers for quad speaker greatness and even vibration motors. If I knew this, I would have purchased it way way earlier. When I mentioned these things to other users they also were like "Wait what?".
I don't care to much about the mobile dock, since I'd just prefer using my docks that I have around which are compatible with other devices, but the twinview was actually fking amazing, sadly nobody knew what it actually offered and assumed it was just an expensive thing to add just another screen.
Bring back the twinview and market it properly this time.
