>Just in case, I have a spare E71 and daughter has an E72 somewhere, so we're supplied indefinitely. I do hate E71's bass ackward headset plug (left speaker and mic cable swapped), but then I don't really use the headset at all.

Might be prudent to look for an abandoned E51 now. I use a cabled headset again, after trying a Bluetoothed headset while driving. Whenever call was important, chances were high that headset battery was low. No reason to go cable-less, just keep a shirt with a breast pocket in car for T-shirt driving time ;-)
