I use my Livingroom computer for both browsing the web and as HTPC.
When I watch a movie I want grab the remote, and I don't want to mess with the keyboard/touchpad.
This is a simple GUI script that starts XBMC, but gives you time to cancel it if you don't want to run it.
It uses the GUI script program Zenity, Ubuntu has it installed by default. The method run it in startup will vary by distro. You can add a startup item in the startup preferences. I use Lubuntu, I just added an entry to /etc/xdg/lxsession/Lubuntu/autostart
