Well I was thinking I would like to write some reviews, and one that is interesting to me is Veta Universal 1.0 from http://veta.irowan.com/index_s60.html
It is for controlling certain programs on you Mac like iTunes, DVD Player, and can even use it as a Mouse controller.
I am most interested in the function were it can change the state of the computer when your phone is in range like Volume (mute), Activate/DeActivate screensavers, and so on.
