Of course you will be able to find something a little lighter than Safari or Firefox. There have been a couple of good suggestions. But note that a large part of the code of modern browswers really goes into the rendering, not the extra features on the side. If you cut on the size of the rendering engine, you either run into issues when displaying some pages (e. g. many mobile browsers) or speed. In that respect Safari is already quite lightweight (which seems strange, as it can use hundreds of MB if available). Remember that its core is used on mobile phones! And the Firefox developers have made a great and successful effort in that direction with Firefox 3. Björn
