Again, there's nothing special available on this Nokia browser but if you are curious about what Nokia has to offer, give it a shot and see. I would also like to recommend this browser to low-end smartphones, the browser is light-weight, doesn't support many features, therefore if your device seems slow or has a poor CPU, you might actually enjoy this browser.
Your device does not have to be rooted in order to run this app. Just download and install in usual way - just like any others.
