Cons:

• It has all the text, but only the first few pictures.
• It's huge (over 750kb) so it takes a while to load
• Some of the text formatting was lost, so it can get a little confusing

Pros:

• It's online, so when you're at your friend's house and can't remember how to do something, log on and there it is

Enjoy.  Please note that I don't have Zoom's permission to do this, so you might want to download the html file in case I have to delete it at some point.
