Do we really need to see a marketplace where people can buy Chrome browser extensions? Well, I guess it could work. Android’s marketplace has done fairly well. But will people be anxious to buy some extensions, even if most of them remain free? I tend to doubt it.
Now if we see Chrome embracing feature rich apps instead, well, this very well could be enough to get people willing to drop a buck or two on some cool applications. Apps that are able to sync data and further blur Web from local software could could do well in this space.
Now the real question is whether or not Google can take something like this, being first to market, and make it cool. Opera has bounded around this area for a few years now. However, its widget approach never really took off to a point where it changed the way we looking at software, either. So until Google rolls this out the door, it’s anyone’s guessing game.
