As a mac user, I am constantly cleaning out my apps folder for apps I don't use. But, I'm not sure if I should do this, should I keep them for future reference, or do as I do now. So, to make a better answer for myself, I wanted to see how many apps you have on your computer, including utilities and Hard Drive size. I have 90 apps and I have a 250 GB HD. (I did this by looking at the bottom of the finder windows and looking at ## items.)
