I remember the good ole days of USB technology. Wow, that guy must be rich! Such a simple yet helpful invention. Later came 2.0 and 3.0. Biggest noticeable change was improved speed, and they kept it backwards compatible (yay!). Great technology, but not so universal now. I need adapters for darned near everything. Now I need a guide so I know which one I'm buying for my cell phone, which is different than my 7200, or my wife's cell phone, etc. Well, at least this may help a few people. Maddening that 'universal' would mean you'd need so many different adapters and combinations. Most of these images are from Amazon, so that you can know which one you need to buy.
