Sunrise is a web browser, very light one - based on WebKit. the URL: http://download.cnet.com/Sunrise/3000-2356_4-83356.html On my PowerBook 12" 1 GHz it is running circles around Safari (both have the options for plug-ins disabled to block all the Flash tragedy). Upon start the browser is using 17-20 MB of RAM compared to around 40-50 MB of Safari. Web pages load in no time and start-up time is instantaneous compared to Safari. due to limited resources on my Powerbook I prefer to open Sunrise far more often than Safari, especially when running multiple applications at the same time.
