Um. My HTC Vogue with WM6.1 multitasks quite nicely. I can easily run half a dozen different applications concurrently, and yes, music does continue to play either from local storage or 3G streamed while another application is in the foreground. Personally I found Android Froyo on the same device to be quite frustrating from a multitasking perspective. Perhaps that was because of the implementation on a device with such low RAM available.
Operating System: Genuine Windows XP (Service Pack 2 or Service Pack 3); Windows Vista (Gold, Service Pack 1, or Service Pack 2); Windows 7.
Restrictions. 1. The software may not be used on a device running an enterprise version of a Microsoft Windows operating system.
