From: Metspitzer on 11 May 2010 18:20 I ended up in the hospital for the weekend. I had no charger for my phone. I also had nothing to do but think. My TV has a USB port. I was wondering if a USB port like that could charge my cell phone? If the TV in the room had USB port it would be a pretty handy thing. Also, my car came with a cigarette lighter in the ash tray and another one on the console. It would seem that newer cars could come with a USB port also. I have seen car ads with cars that come with a hard drive. I would think having a USB player would be even better. Everyone could carry around their music on their key chains. One hitch is that there seems to be a endless number of proprietary connectors. As far as I can tell. 2 or 3 types should be the limit, and anyone using a proprietary connector should be shot. Doesn't the U in USB stand for Universal?

The standards bodies just can't help themselves, when it comes to inventing an endless supply of different connectors. If a "micro" connector is such a good idea at any point in time, why isn't it introduced from "day one", so there is only one connector to choose from ? Why start with a "macro" sized connector, only to make a "micro" one two years later ? http://en.wikipedia.org/wiki/Usb http://upload.wikimedia.org/wikipedia/commons/c/cb/Types-usb_new.svg Further down that web page, is a list of non-standard connectors, used by various manufacturers. In terms of things like cell phone adapters, there are moves afoot to change the situation with powering. Eventually, all cellphones will use the same adapter. http://news.cnet.com/8301-10787_3-10167129-60.html "The Micro-USB connector used on this Motorola cell phone charger will soon be the standard for all chargers." So cell phones at least, will eventually be fixed. But there is nothing to keep other branches of the industry in line. Paul

A quote I think attributed to Andy Tanenbaum is apt: "The nice thing about standards is there are so many of them to choose from." James |
