Chrome has a lot of hidden pages starting about: and these are quite hard to locate. After looking in several magasines including PC Pro and also scratting around on any search engin apart form google I found the following, so I listed it in case I forgot again. These about: pages allow you to get lots of completely useless information, butthe are fun to look at. you just type in about:dns say for the hidden about page on DNS inside the browser.
To be honest the only really useful one is about:plugins thou about:memory is interesting if only to debunk the theory that IE is more bloated then chrome.
