Whenever possible I get the wireless versions of all the gadgets I have around the house. Wireless keyboard and mouse, wireless networks, wireless controllers, wireless extension cords (just kidding about that last one. Would be cool though). I had the good fortune today to get wireless headphones that work with my computer as both headphones(I'm actually listening to them right now) and a headset, my phone as a bluetooth headset, and soon as a wireless headphones for the music on said phone. It's the coolest thing. I'm even giving it a plug (wireless, of course) with the Amazon link.
The downside to all of these avoidance of wires is the box of chargers that I now possess. Wireless still needs electricity, and while better than buying tons of batteries, why can't there be more of a standard chargers that more devices can just share? Having something run out of batteries is a minor annoyance. Rummaging through a box of chargers to find the right one is just plain crazy.
