Well, I had download problems with it, I download 1 thing and anything I downloaded after that would either not start or finish corrupt. The exact same thing happened on my phone.
Sometimes it would not load pages properly, sometimes it take forever to go back. I put up with it for a bit because I did like it but I went back to using FF and had FF portable and it was way better with Java and a lot faster so I went back to that. At work I use FF to get on the service desk software to view my jobs and in FF it loads instantly as its Java with opera and IE and google chrome it takes ages.
