AeroBrowser is a free next-generation web browser based on the look of Longhorn. It is small in filesize, completely spyware free, and doesn't track your history. It is based on the IE engine, but future releases will include dual-engine switching capability with both IE and Gecko.
The next beta will be released within 2 weeks, and it will be mainly a bugfix release. The beta after that will probably have new features such as tabbed browsing and pop-up blocking. Plans also include implementing a skinning engine that will allow you to customize the browser to your liking.
