I have a feeling Tom is going to chime in with regards to migrating computers. But I'll say that I've never had a problem with with my wife's regular iPod nor my iPod touch with multiple computers. Not with migrating from one computer to another and not when using the device on multiple computers.

The highest level comment I can make is that when you migrate from one machine to another, all your data and settings, including your iPhone or iPod stuff, moves to the new machine pretty seamlessly.

In any case, I was curious if this wipe-everything was an Android design or just something else that HTC has screwed up themselves.
