It seems like all of the browsers now import data from other browsers when you install them. So, is that really much of the case?

Beyond the old stereotype "grandparent thinks the E is the internet", there is not much of a difference in how each browser behaves. The UI's are shockingly similar.

If it was, I would not think that Google would be as successful as they are to push Chrome heavily. Users would not transition over.

I will admit that I do sometimes have a different view of technology than many people, I mean as it is I have multiple browsers running right now. And generally when I step back I can see, oh yeah this really may be a bigger deal for most people.

I am struggling to see it in this case, especially with every browser trying very hard to make it as easy as possible.
