Mobile Witch Remote Control is a software utility that utilizes Bluetooth technology to enable your mobile phone to be used as a remote control for your Desktop.
Overall: The keyword here is Bluetooth. This is a fairly decent tool but note that it requires Bluetooth at both ends – the PC and the mobile phone. Since it uses Bluetooth, although it does function as a remote it has certain range limitations (a traditional infra-red remote has better range) and is also susceptible to interference, especially from Wi-Fi (which is definitely going to be on your computer). The other thing is that the software probably hasn’t been tested for compatibility with a wide range of mobile phones: there are some issues here with navigation etc. To some extent the navigation problems are also due to the limitations of the software itself, in that it only functions on the Windows that are on top and only a handful of applications (that need to be started before one can use the remote control). It is best suited for media applications such as controlling the Windows Media Player when watching a movie or managing a PowerPoint presentation.
