I'll add one thing, relative to our earlier discussion: I have a variety of USB cables around the house. Some from old phones. Some retractable. With the crappy ones, you plug them in and you never know what will happen. Sometimes the phone just flat out crashes. Suffice to say that the Galaxy Nexus is sensitive to crappy cables. Don't use with a crappy cable.

And, to gratuitously summarize the whole other thread, there are Apple chargers and there are standard chargers. Random third party chargers often follow the Apple non-standard. A handful follow the proper standard. Make sure you get proper standard chargers.
