- Trackpad is decent. However, as some others have mentioned, it can be a bit touchy. It's happened a few times that I'm typing and I accidentally rest part of my right thumb on the trackpad and that changes the insertion point inadvertently. Not a big issue. As a matter of fact, it's more an indication that I need to correct my hands posture for better ergonomics.

- Bluetooth. It's pretty stable. I have a Bluetooth mouse and Galaxy Buds connected and they work flawlessly. I'll try more devices.

(edit: added Galaxy Buds over Bluetooth)
