You do know that that ... thing ... is just a wrapper around the Internet Explorer engine, right? It's not a browser in its own right, and it will not help people who for some reason are using pre-XP versions of Windows to use modern web pages.
So, let's look at the claims again: Tiny? Well, yeah, considering that most of the infrastructure is provided by IE. Portable? Again, yeah, but it does require IE to be installed. Works great? Yeah, about as well as IE does.
Hell, the only reason to use this is if you want to browse anonymously and without cookies but somehow haven't figured out that the Incognito modes available in Chrome allow you to do just that. Just look at the "user stories" section, all full of people who somehow got embarassed by having the porn in their search history exposed.
(In their FAQ, the developers state that they're working on a Linux version. I wonder how they're planning to do that)
