Well work was so kind to get me a little macbook pro – already got windows xp on it, and just need a couple of versions of solaris and i’m set – but found http://blog.medallia.com/2006/05/smacbook_pro.html little app for controlling the light sensor and using it to switch virtual desktops. Very nice, the right hand sensor seems a little odd tho – but one is better than another and it is a neat party trick for those “these are not the windows you are looking for” moments.
