Julien Schapman has released a video preview of his Windows Phone Device Manager and it literally makes a mockery out of the currently PC – WP relationship that Microsoft is shipping (which is just Zune syncing actually). Just take a look for yourself:
This is just about all you could want. Transferring files, setting ringtones, using local clipboards, sending texts/emails locally (through your phone), managing applications, etc and it even works over wifi. Fortunately, he is seeking to be part of the official homebrew development team so hopefully Brandon Watson and Microsoft are actually paying attention to things like this and they realize that this is something to adopt of emulate.
