I simply can't see how these devices are going to stand up to the presumably harsher conditions, and rougher treatment - you have only to see any Forum to see how fragile they are in our pampered surroundings, and with expensive covers too.
And we can, mostly, I suggest, better afford to replace ours once we've found them essential equipment.
Unless, that is, the technology has suddenly become more robust - or should we say,
can be more robust........

Too much to hope we also see it, if so ?
(Oh, and the production costs can be trimmed - or more probably "cross subsidised".)
