NMC can still be found in things like handheld power tools.

Today, Li-Po (Lithium Polymer) and LCO (Lithium Cobalt Oxide) are 
typical options for mobile devices.

Back when we spent quite a bit of cash on camcorders, we experienced 
plenty of NiMH batteries. It's quite an inferior battery, but it served 
its purpose well, at the time.

I still find NiMH batteries shipping in modern gear today, e.g., low-end 
electric toothbrushes. I generally avoid these where possible, and buy 
Lithium-based toothbrushes :-).
