Tony,
I'm trying to use the media library portion of WA to make finding the songs easier than traversing the file directories in explorer, so adding the send to to the explorer shell wouldn't really get me there (IIRC that's done with a PowerToy?). This is primarily so my wife can send songs to her flash based Samsung Yepp, as the software that comes with the Yepp is junk, and for some reason M$ Media Player's library refuses to add any songs to its library. [actually, I just fixed that by deleting *.wmdb]
So, I guess I can use WMP for now, but I'd like to use WA in the same way (Send to: Portable Device).
