Iterating

I often see code like:

Iterator i = list.iterator();
while(i.hasNext()) {
    ...
}

but I write that (when Java 1.5 isn't available) as:

for(Iterator i = list.iterator();i.hasNext();) {
    ...
}

because

• It shorter
  
• It keeps i in a smaller scope
  
• It reduces the chance of confusion. (Is i used outside the while? Where is i declared?)
  

I think code should be as simple to understand as possible so that I only have to make complex code to do complex things. What do you think? Which is better?
