Little dongly things

Matthew seems to have forgotten one of many chargers. PDA, notebook, GameBoy, mobile phone, digicam – there are soooo many of these to think about. Not even counting the special cables you need if you want them to interact.
That’s obviously an area where we haven’t learned anything. 5 years ago (as it seems from the URL – EXACTLY five years ago) the late Douglas Adams wrote a funny piece (did he ever write anything serious?) on the same topic.
Can it really be so hard to agree on a common set of few connectors, and then stick to it? Is there really money to be made by differentiation? I don’t think so. Come on, cooperate!
(Witty remark: I thought about putting this into my “wireless” category for a few seconds…)
