ZDNet colleague, Jason Perlow, posted an article a couple of days ago about hisand I too think it is a great step forward. I love that I don't have to worry about which direction I insert the connector, but have been quite annoyed that I could not charge up my iPhone 5 at home and work without carrying the dang cable with me at all times. The new Lightning to micro USB cable that Apple just released is the exact adapter I have been wanting since the iPhone 5 release.
I have something like 20 microUSB cables with USB A/C chargers around my house and office that power up my smartphones, tablets, headphones, and ebook readers. I was willing to buy a second Lightning USB cable, but they were never in stock and no stores had them. In the past month, I have forgotten the cable at home a number of times and had to limit my iPhone 5 usage to make sure I had enough juice to get home. The new Lightning to micro USB adapter costs the same as a Lightning USB cable ($19), but given that I use more than just my iPhone 5 I will now be able to take one cable (along with this adapter) on the road when I travel to keep all of my devices powered up. I purchased two of the adapters so I can now have a power cable at work and in my car, along with the one that came with my iPhone 5 sitting at home.
