“this is so good. you can plug normal USB devices into your PiZero. Yes there are adapter cables out there, but for an WifiDongle e.g. you don't want to have a cable wobbling around.
Just one disadvantage (but this is more a PiZero Problem): when when you use more than one of these Dongles, it could be, that the 'real' USB cables do not have enough space and you cannot plug them in. but... thats not a real Problem, because you do mostly use one normal microUSB for power und just one Dongle and thats fine.”
