There is a use for it
There is a use for beeing able to remotely log onto your mobile phone to execute applications on it. In developing countries, the first computer most people have will we a mobile phone. Now imagine a small business running some management software in a phone. Eventually they will want to have a bigger screen and keyboard, but they don't want to loose the possibility to have everything on the phone. Just loging into your phone and executing the phone applications on a large screen would be usefull then.
However Windows Mobile has the problem of beeing incompatible to the rest of the world. Therefore there are only few applications availiable for it.
