USB - Universal Connectivity
A friend once told me that USB is genius. “You can charge your device while transferring data. Brilliant!”
This was before Apple made connecting your handheld to a computer via a USB cable (called ‘sideloading’) for transfering media, an everyday household activity. Over the last few years, USB has slowly but strongly emerged as the de-facto connectivity standard for all devices – especially mobile handhelds. People download small multi-media files (ringtones, songs) over their wireless networks, and with 3G/4G, this will continue. But the content is getting bigger (HD movies are now >4GB). Storage on the handheld is increasing as well (32GB SD cards are easily available). It may take hours to download this type of content over the air and forget about your battery life or the network connection . USB is keeping up with this, and with USB3.0, I have no doubt that it will be the connectivity standard of choice. I found it very interesting to see that the topic de jour last week – Apple's introduction of its new iPad highlighted the fact that it "syncs over USB just like an iPhone or iPod".
The simplicity of connecting my phone to the computer for a quick ‘synch and go’, and the flexibility of charging it while I drive to work everyday, always remind me of my friend’s remark about USB – “Brilliant!”.
