Thank goodness for screen sharing. My in laws called earlier, with a printing problem. They use an iMac, so I figured I could solve their problems if I could look at their screen. The bad news: they didn't have a Google Chat or AOL Chat account, so iChat wasn't an option (I figured walking them through setting up an account from scratch was going to be truly painful). Fortunately, they do use skype, so all we had to do was get the latest version installed. Once there, we were able to share screens, and I was able to spot their problem. Not quite as good as iChat (where you can control the remote screen) - but better than hopping in the car and driving all the way out to where they live to solve a small problem :)
