Replace memory hogs- from Matt Thompson

From the nerdery--

This link is a list of free software apps that can replace Microsoft-brand programs. Why does this matter? Aside from sticking it to the man, these apps are great because they consume much less memory than your more standard fare, thus your computer runs faster. Yay!

Update: it's not just for Microsoft brand programs, but things like Adobe Reader, AIM, and the like.
