Chrome is n00b-friendly, and that's where its appeal lies.

There is no way that users who appreciate Firefox's strengths will move away from it.

IE can be rolled out via Update, they have their market share.

If Google want to compete, they have a lot of work to do, bringing it to Android will be essential, for example, and despite its speed increments, it's easy to say that Firefox or IE or even Opera - is simply fast enough.

There are a few loose-ends on Chrome and if Google don't realize that they NEED to appeal to as wide a user base as possible, they're not going to do well.

Anothing thing to look at, is the 'Apple Effect'.

When Apple launches a new generation of iPods, its a massive deal, always, if they launch a new product altogether, it generates a hell of a lot of discussion, press and general hype.

Google benefits from the same, they are a fashion icon like Apple ~ when they announce a new service, like Gmail for example, it generates waves of interest and everyone want a slice of the cake... the infinite internet cake. Chrome will massively benefit from this, per sé, I saw 'Google announces Internet Explorer rival' on the CNN Business Ticker, and a lot of people watch CNN, and they aren't going to be the only mainstream media to report on it, either. It'll be one of those things that wee have to do - try it out because everyone else is - and this is how Chrome is going to get a strong start and fanbase.
