Weirdly, none of the many phones, tablets and laptops I've owned have ever caught on fire.

It’s not as much about the risk of failure, as both are safe when the correct safety measures are in place.

But what might happen when they fail - thermal runaway is no joke with lithium-ion, ask any firefighter.
