As a user of the E485 (basically a budget version of the A485) I can confirm, and agree with, everything but one thing here. Regarding your Bluetooth issue, what chipset do you have? I picked a Qualcomm one on mine because I had bad experiences with Realtek before. Never had an issue like yours with it.

For me its quite a usable machine now. But I'm currently giving a M1 Macbook a shot and it certainly is convenient not to have hiccups like this (yet).
