Google Chrome (BETA) for Windows
http://www.google.com/chrome

Google Chrome is a browser that combines a minimal design with sophisticated technology to make the web faster, safer, and easier. One box for everything – Type in the address bar and get suggestions for both search and web pages. Thumbnails of your top sites – Access your favorite pages instantly with lightning speed from any new tab. Shortcuts for your apps – Get desktop shortcuts to launch your favorite web applications. I downloaded this at 3:10pm EDST today and works fine and seems to be quite faster than Explorer 7.0 when I use a number of applications and surf several active sites at once. I have added this to the tools section of Research Resources Subject Tracer™ Information Blog.
