I've been trying it again for a few hours in MSIE7, which I normally never use because it's so slow compared to Opera. Surprise!! Running with the Private Browser engaged, there seems to be no slowdown at all. It actually loads pages on this PC almost as fast as Opera. I gave an earlier beta a try and dumped it because it slowed down IE7. Don't know what they did to it, but I'm actually seeing a speed increase now. As far as being as safe as Returnil, SafeSpace, etc against malware I have no idea, but I think I'll keep playing with this latest beta for a while. I kind of like it, and I'm not fond of ZA products in general.
