Even when powering electronics in the home, you have to worry about which sort of power the device needs. Does it need a great big 240V AC outlet, or just the regular 120V AC (using American values...)? Is the device DC powered instead? Does it have it's own wall-wart, or can you use a AC->USB converter? Does it use USB micro or mini? These are things the consumer has to worry about. Of course in practice "worry about" is an exaggeration; this is all pretty elementary stuff and no reasonably intelligent consumer actually loses sleep over it. The matter of what version control to use? The consumer never has to worry about that. That concern is something that only developers (and related professionals) will have to worry about. I don't think it is a big deal. Just pick whatever fits your needs and that you prefer. Should the developer have to know anything about version control? I don't know, should the electrical have to know anything about multimeters, outlet testers, and wire cutters?

Does it need a great big 240V AC outlet, or just the regular 120V AC (using American values...)? This isn't accurate as to the electronics that I use. All the adapters say "input 120 - 240V". Non-portable electronics tend to be compatible with the plugs in the same area where you buy them... since they're not portable.

  The parent comment didn't refer to the 120V / 240V distinction because of the voltage itself, but rather refers to two distinct kinds of electrical sockets. 120V = NMEA-5, 240V = NMEA-6 http://en.wikipedia.org/wiki/NEMA_connector http://en.wikipedia.org/wiki/NEMA_connector When you install a washing machine (or, for example a circular saw in your workshop) you'll have to make sure that the proper socket is available at the place where you want to put it (or you'll have to install one at that location). In Europe, the corresponding comparison would be between 1-phase (230V) power and 3-phase (400V) power, e.g. normal household socket and the red, round 5-prong CEE connectors. http://de.wikipedia.org/wiki/CEE-System http://de.wikipedia.org/wiki/CEE-System
