I think Bot Obi is specifically referring to the preset "zoom steps". 
They seem to be fixed at: 12.5%, 25%, 50%, 66.7%, 100%, 150%, 200%, 
300%, etc. regardless of the method used to zoom in and out (zoom tool, 
keyboard + arrows, keyboard + scrollwheel)

I have Photoshop 7 running in Wine. It has the same or very similar 
preset steps using the Zoom tool. However, using the keyboard shortcut 
Ctrl + Alt + scroll (or Ctrl + Alt + Shift + scroll) you get a sort of 
proportional step. When you are zoomed out below 50% the steps go from 
5% down to 3% and 2%. Above 100% the steps go from 10% to 14%. Beyond 
300% the steps are a little over 30%.

So the steps are something like 10% of the current zoom state rather 
than the fixed steps. It makes for a very “smooth” zooming sensation.

Granted, Photoshop 7 was released in 2002. At work I have CS3 and will 
have to experiment with that when I get to the office.

It certainly would be cool to have this proportional step zoom instead 
of the preset steps. Or possibly as an option. Or maybe just available 
via the keyboard shortcut. I wouldn't be surprised if some workflows 
relied on the fixed steps... for pixel-perfect icon designing maybe?

Hope this info is helpful.
