I realize I am very PC-centric here, but I do appreciate the Macintosh universe. As a matter of fact, I used to work for a grant-funded project at Montclair, and they gave me a Macintosh laptop to use, and I used it for a few years.
One of my friends has the iPhone, and he showed me a tool called "Telekinesis" - this is a tool that allows him to control his Macintosh from the iPhone. It turns out this free tool is one of a few from a group called Blacktree. They've got a few other tools as well. If you're a Macintosh users, their site is worth checking out.
If you're reading this over the break - I hope you're enjoying your time off as much as I am!
