Hi Alistair
All good valid reasons.
but for me
(1) my compression was a one off procedure - now over, i don't often get new CDs
(2) seems that way I agree, but I need my B2 connected to internet anyway to get YouTube, Radio, connect to my Sonos and run the music NAS. To ensure maximum stability I connect my B2 via Ethernet cable.
(3) There you DO have a universal common reason :-))
did checking the battery life and or orientation help at all? I have had to change the handset battery once (recently) since 2016 (but as you can gather it is not used much)
