I use it as my explorer. It's okay, I loved it in the beginning, but it randomly crashes for no actual reason ALOT. And for some reason, it now hates various flash related things, for example I can't view any videos unless they are youtube, and even then only on youtube itself.
If I could, i'd go back to IE, but for some reason, I can't get it to work at the moment. And Firefox is randomly slower and generally a pain to use on this computer.
