I would refine this:

Never use them for anything that does hardware accesses or has hardware 
dependencies.

I use them quite a bit for packing data into software structures because this 
allows me to do bit-wise packing without writing a whole bunch of shifter 
code. Being able to bit-pack structures easily can save a lot of space when 
creating large numbers of them.
