Mainly to save wear on the usb flap. But also because the micro usb lead is extremely hard to remove without feeling your about to tear the port out. I opted for just a usb charger rather than a dock. Anyway I have to say it's the hardest thing in the world to line up. In the dark? Forget about it! I imagine it works great on a dock. But the terminals are so small trying to align them whilst the magnet is trying to pull it down. Am I doing something wrong? Im just finding it extremely difficault.
