For the cellphone: You may end up carrying TWO cables... One to charge, the other to communicate with. For those who never want to sync with their phone and/or upload download stuff, no problem. Else, figure 2-cable system soon.

I personally think that Nokia was the most consistent... For the longest time, ALL Nokia phones use the same plug, so any Nokia can use any other Nokia's power plug. It wasn't until maybe 2-3 years ago that they came up with the "ultra-sharp" needle adapter, and suddenly you can't buy the old kind any more. :P The worst offender? LG. They have at least FOUR, if not more, plug designs, at least that's what comes in the package when I buy a LG adapter. :P

What other device needs a clean-up? How about laptop power adapters? Every company, every model is different. Sony has no less than a dozen different adapters of various voltages and sizes, even though as far as I can tell they all seem to have the same plug. And those "universal" ones sold in stores... They don't seem to sell a tip for the Sony series I got. I had to order one off eBay (which is much cheaper than one of these "universals" as well).
