Hi margarita -
My first fear is that Google will make Apple Webkit as a rendering engine standard due to its powerful media and the money spent in Mozilla Foundation.
Just like the Trident engine, and the Gecko engine?
I'm close to being a "Senior Citizen", so I remember very well the "Browser War" between Netscape and Microsoft. That actually led to improvements for the 'net community: for example, the resurgence of MS IE in v4.x as opposed to Netscape v4 which was a complete disaster. IE4.x showed how even the mighty Microsoft could listen and (more importantly) actually respond to user input and thus produce a vast improvement on IE3.
I see the current tussle as a more sophisticated extension of BW1. IN BW2, we get the benefits of four (Trident, Webkit, Gecko and Presto) really well-found engines all competing for our favours. I also see the multi-engine browser shell increasing in popularity.
I don't mention it in my sig, but I use Sleipnir 2.9.6 as a very useful wrapper for IE6 SP1, mostly because it offers true tabbed browsing with only a single instance of IE -- which MS seems to have only recently achieved. Memory usage with Sleipnir is extremely reasonable (I have only 512MB RAM). Sleipnir also offers the use of a Gecko engine, but this has been suspended due to perceived "vulnerabilities".
So I look forward to continued development of KM/Gecko, whether as a single-engined or multi-engined browser of first resort. (IE is my browser of last resort
