Here is my desktop on my school computer. It isn’t always this cleared off, but I try to keep the number of icons down. Notice on the bottom task bar I have 2 Firefox browsers open. One is for my Ustream channel showing my classroom, the other has my email, blog, and whatever pages I have open on it. I usually keep Windows Task Manager up because I like to see what is going on “under the hood”. Next is Netop Vision which allows me to monitor and remotely access my lab computers and finally I have TweetDeck open which I like to browse when I have a few minutes.
You may also notice I have the quicklaunch toolbar running, I love being able to easily access an internet browser without having to close or minimize what is on my screen.
