Headline I agree that this device is a junk
Text Especially with Micro$oft mobile OS. It constantly freeze, and now with the 6.1 upgrade, it refuse to play any song on my card and even won't allow me to move files from card to it's own storage. I start to realize why so many people hate Micro$oft after I quit it. Yes, I worked there. They do NOT care customer and they live in their own world. I know they test their junky softwares using supper fast computers in "vacuum clean" condition and claim they will "work" in real world. I also blame myself being a software engineer for years and could not figure out how to use a PDA phone.
