This one had completely slipped under my radar.
The idea of running a browser in a virtual environment isn't new. In fact; it's a core quality of IE 7, which I guess means the idea is mainstream, if Microsoft is doing it.
My idea is that this is a decent product, but too late and over-priced, to boot. $49.95 a year is a bit much, considering I can get about the same thing by switching over to the beta of IE 7. No matter how one views it, this is proof there are more people thinking about the security of IE than Microsofties, security researchers and journalists.
