Karim Azmy NOTHING is not big on customisable buttons, see ES buttons. So, I think (3) is out. As an aside, I remain pleased that the live translation on the AirPods is blocked in the EU as I would like to know where my voice patterns are being sent (hopefully not to the US for deconstruction/translation, given its current administration).
NTL needs to be careful with the flip2record as they could easily run afoul of the same EU-based legislation. (I am unsure which jurisdictions the flip2record is offered within currently.)
