Nokia has acquired Chicago-based mobile Web browser firm Novarra.
Eleven-year-old Novarra is known for developing the Vision browser, as well as platforms to serve content, advertisements, and analytics. It previously supplied its technology to Palm and U.S. Cellular. [Official Nokia statement]
I think nokia is thinking about depending on free or open source software instead of developing a browser by their own. Making a new browser won't benefit them much since opera mini or other browser will provide same facility also.
For example, my phone is nokia 2323. It's a low budget phone with basic internet and java support. So nokia has provided no nokia browser in this phone. Instead they've provided opera mini.
I think they've employed their software team in planning to develop applications for browsers so that people use nokia phone more rapidly. Making a browser wouldn't force people but an application that run only on nokia will definitely force.
