Saw this on NeoWin about a new browser out there based on the IE core and soon to be a dual core browser with Gecko called Aerobrowser. From the NeoWin post:
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.
I've downloaded it and about to install it, but I'm not really sure about how this is gonna be a "next-generation" browser since it's already based on this generation browser. You'll still be suspect to IE's already lacking CSS compat and it's security holes. It's basically a way for people to customize thier machines to match Longhorn's look and feel and nothing more. If your looking for IE core browsers check out Maxthon(was MyIE2) for a better implementation. Either way, it's done in .Net 1.1 so I guess that's cool.
