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.
Crazee Edeee, his prices are INSANE!!!
