I have been using the new Google Chrome browser ever since it was released towards the end of last year, There are two versions you can downloa - a stable version and a more recent beta version.
I have been running the beta version for the last few weeks with no problems at all. What I enjoy about Chrome is its minimal user interface design and the fact that is blindingly fast and has some cool features.
If you have not got around to checking it out yet I suggest you do.
