The N900 and certain Blackberry models, and I am sure, probably countless other devices have microUSB plugs that requires a "smart" charger that can negotiate for power. This means that a standard USB charger that provides standard USB power and cannot negotiate about that, requires a cable where two of the leads are shorted. In other words, the standardization to microUSB has lead to most standard USB chargers being useless. If you believe that this will NOT come as a surprise to almost every owner of a standard USB wall/car charger, then you are living in a very special world. I can assure you that this is not mentioned in a single of the reviews that this thread says we need to read before we're deaned worthy of buying the N900. And if you expect EVERY PERSON who wants to buy the N900 to realize they need to research EVERY THING about the device that might influence their usage on this MICRO level, as to "can I expect the microUSB cable I already have to be compatible to the microUSB cable that I would need to charge this device in my car", then noone would ever get to the point where their research is done and they can buy a device. And no sain man would expect people to read "MicroUSB charger" and think "I need to research if MicroUSB is compatible with MicroUSB". Seriously. I mean. Come on! I tell you, some here have a totally twisted expectation to what people should be expected to know. Is your spare time worth absolutely nothing to you?
