RAM Upgrades Are A Wonderful Thing: Let’s take a little survey: How much RAM do you use?
I can’t imagine using a modern computer with less than 1GB of ram. When you factor in Thunderbird, Firefox, Emacs, two IM clients, Office Apps, PuTTY, the Gimp, and the various other stuff I run daily, it’s not difficult to see why.
I have 748MB at work and 512MB at home. 512MB seems like plenty to me.
