This app has 2 main functions, firstly you can use your touchscreen as a mouse for your pc. Secondly you can stream music from your local pc. Overall it works well, I could imagine the mouse function being useful for a media centre pc. The interface isn't exactly enthralling, but it does the job and hasn't given me any f/cs. the music streaming could be quite useful if the interface was jazzed up a bit, but mostly this app is useful as a replacement for your mouse, and that it actually does incredibly well. You are required to download the additional server software, but it seems pretty light weight and not a big bloated piece of software.
