I don't know, I've used a lot of winmo phones and not only is the interface pretty terrible but I really never saw it do anything particularly breathtaking, especially nothing over what I've seen android do.Because you can pretty much do anything with it (including plug in serial devices if your phone had a socket for it). Android is closer than ever but it still doesn't have the breadth of WinMo and even with the latest update iOS really isn't in the same league.
I don't really want to particularly off topic in this thread, also you can get serial cables for Android devices
