British Ban Carry-On Laptops? - Dangerous Common Sense

The news is reporting that one of the new British airline rules is to disallow liquids and electronic devices such as laptop computers from plane cabins.

Last I knew, the baggage claim checks specifically say that there is no liability for a number of things including all electronic devices. About 10 years ago I checked an old laptop, it was stolen, and I was told tough luck and pointed to the claim check wording.

If laptops, phones, etc. are banned from carry-ons, will airlines step up to insuring checked electronics?

If they won't, and banning electronics becomes widespread, this seems like a potential huge hit to laptop makers if not other electronic makers.
