Fair point! BUT, aside from being able to use the handsets as a digital phone book, they ARE useless in all other regards, are they not?!
Also (sorry for being a 'pedant' again) ; , but the original question was:
"Most people have cordless phones. How do they work in a blackout?", which was only really answered with the batteries line... so they'll only work up to a point!
Which is why I made the point about the issue with batteries, end of! ;)
