I think buying the Sony MW1 is having me rethink my music situation. Personally, I love it. It allows me to kill that and not worry about abusing my WP's battery. Now, when I leave the bluetooth on constantly, that's a no go. I had it paired with my Z Ultra today and got about 6 hours of consecutive use - playing music off the SD card and being paired throughout. I think o will end up getting the Sony SBH-52 and using that exclusively with the Z Ultra. My battery would go to **** with both the SBH-52 headset and the SWR10 smart and being paired simultaneously, but I gotta figure that one out before I buy it.
That's the thing I'm noticing with Android. Because of the existing maturity of the OS, you can take advantage of fresher concepts and hardware. I'm curious to see what enhancements MSFT add tk the OS and how they tackle wearable tech.
