The vendors bought you a good lunch as well then?

The effort involved in switching OS is never identified correctly by those who want to make the switch. If it was, no one with anything worth switching would do it.
They've already decided that it's worth doing. They don't want to hear problems they want to hear solutions, yada yada yada.

The cost of doing it for anyone with any real embedded IT in place, vastly outweighs any benefit real or otherwise from doing it over a period any competent business person would deem sane.

You should switch to Chrome and the cloud is no different to "Go Linux" There is no justifiable business case, tell it like it is. You don't like Bill, you think Stallman is a commie, you will get paid a shed load of money for doing it.

Just stop with the crap already.

Would Chrome be a suitable solution from scratch, maybe. Would it be something you might want to hybridise with and move towards, maybe.

Just up sticks and switch in toto is bollocks.
