Hmm.. about the cached sites.. this is usefull if you are at work or school, and they block sites. Alot of the times, they block the IP address of the sites, therefore you can not get to the site, but... if you use the Google Cached version, it is not that site's IP address, it is Google's, so unless they have google blocked as well, you can get to the site on the cached version.. :-D
