If I need to use a modern web browser on the open web it is generally because I _need_ Javascript. Bank, etc.
Most of the time I can get what I'm after without using a web browser, and when I need to browse HTML I can do it with browser that has no Javascript engine linked in.
It all depends on what the user is trying to do. And not all users are the same.
For retrieving content I find I do not need a web browser.
For reading HTML I find I do not need a Javascript-enabled browser.
Looking at photos is a different task. When I used to use X11, there were a few good options for viewing large number of photos quickly.
Watching video is a different task. For this I prefer a dedicated application. Interestingly enough, the player I use on the iPad has a built-in FTP server, HTTP server... and a web browser. Quite useful.
