There are no big feature changes in the beta version. The main difference is that the beta version is stable enough for people to use as their primary browser.
We estimate that the number of failed/partial downloads are low because we have a tiny application, which is easy to install.
We think the market is ready for another competitor to Internet Explorer.
We're the leading browser vendor on the mobile side of things.
We expected the licensing fee to increase but we have not seen it grow as much as we wanted.
This doesn't only make it load more quickly - it also saves money for those who pay high fees for data usage on their phones.
There obviously is not a standard for this.
