Yeah even the little stuff has protection built-in. With smaller cells, IE phones, PDAs, etc. they usually don't charge anywhere near a 1C rate. Most of them are 1s so they don't even require balancing, just over-voltage protection. The larger ones like laptop batteries charge more quickly and are multicellular. In fact there have been several instances with laptops going "poof". Most recently a batch of Sony batteries.

Also, these are all Lithium-Ion batteries. Not Lithium-Polymer.
