But Netscape ran cross-platform, without which the WWW would have devolved into a Windows-only niche product. And that would have meant the only tablets today would be running Windows.
I don't think that follows. Also, it's not as though Netscape didn't have it's moments either. There was a time where it was better, a time where IE was better, a time where firefox was better, a time where chrome was better, and so on. Time marches on.
