What's wrong with MicroUSB? I have many MicroUSB devices, and many corresponding leads (for charging and the like), and have never ever had one (male or female connector) break.
The MicroUSB is smaller, and I think visually more pleasant. This allows it to be used on ever thinner smartphones and tablets, without worrying about trying to find space for the port. Also, it does not mar the aesthetics of a device, due to it's small and (fairly) flat form factor.
