I used to use GreenBrowser and it seems it's a pretty good browser loaded with bunch of features, except I had some sudden random GreenBrowser crashes without any visible reason. Same thing happened with Avant Browser. I also tried Enigma Browser and Slim Browser in the past, but nothing ever worked as good as MyIE2 worked on my machine. Of course MyIE2 is known as Maxthon Browser now.
Never ever had any problems with Maxthon in the past and it seems like a really stable browser.
I'm sure GreenBrowser works perfect for Bob since I've noticed he is using it pretty long time by now, but I just wanted to add my two cents worth comment. Maybe you Tech will experience similar problems like I experienced, and maybe not... I guess you have to try it to be sure. But one think I know for sure, and that thing is... Maxthon never ever crashed on my PC, loading pages really fast, and it's nice (very light btw) interface helps it stays very attractive for the eye.
Cheers !
