I really like the promise of Bluetooth (short range wireless connectivity that has the promise of eliminating wires between devices). Eliminating wires, or reducing the number of wires needed to function digitally would be a blessing.
But, having just moved I do not find the wires connecting the devices to be a huge problem it is the power cords. There are a myriad of power adapters that require somewhere to be plugged in. It also seems to be a requirement that the power cords are tangled with other power cords. Not only this, but power adapters are not interchangeable. Not only are they not interchangeable, but the do not come with any corresponding labelling that help identify power cord A should be used with device A. Power cord adapter manufacturers should be prohibitited from having their own branding on the adapter, as that branding inhibits pairing the device to the adapter. There are a couple companies that get this, Sony and Apple tend to brand their adapters so that it is easy to get their devices running. I guess the other device companies are not interested in us using their devices, but are only interested in us buying them.
What about daisy chaining power adapters? You know, like Christmas tree lights. Or universal adapters with voltage and wats settings that are selectable and an interchangeable plug end that quickly changes to been the devices connector slot, much like the British electrical outlet plugs are/used to be (have not been since the late 80s and it may have changed). In Britain when you bought an electrical device it came with a cord attached, but the cord did not have a plug to connect to the wall, as there were not standard wall outlets. The lack of plugs on the cord was annoying to those who were unaware of such practices, but it easy to understand why this practice was needed.
So to create a more workable environment have the ability to daisy chain power cords and have interchangeable plug ends. Manufacturers of devices must brand their power adapters accordingly. These steps would help eliminate the umpteen cords I have in bags that I do not know their mated device. I find 12V adapters do not work with all devices that state they need 12V power coming in. All I want to do is follow my digital passions and work. Is that too much to ask?
