Why can't everything be USB?

I'm going crazy with all of the connections I need.

My iPhone from Apple has a special connection on one side of the plug that I use to charge it. Of course, that's different from my last phone, or the one before that or the one before that. I need juice for my electronics so every time I buy a new phone, that means another wall charger and another car charger.

Of course, my bluetooth (yes, my bluetooth) from Motorola has another proprietary connector that I use to power it up. That connector is different from the old Motorola bluetooth.

My camera doesn't do USB on each end. Again, there's another special connector on one end. Of course, that's different from the digital camera that I had in the past.

My plea: let's start making all of the connections universal. Of course, if we did that, Apple, Motorola and every other electronics company out there couldn't take more money from us.

Wanna buy an old charger?
