I have a handful of docks that I’ve stowed away in a drawer because I no longer own the iOS devices I bought them for; they were all bought for specific iOS devices, and they’re not compatible with my latest ones.
With the iDockAll, that’s not an issue, because it’s designed to fit any iOS device you own — including your iPhone, your iPad, and your iPod touch. It looks darn good, too, and it doesn’t prevent your iOS device from being used while it’s charging.
