Woah! I had no idea about the "application" feature of Chrome! That is so simple, yet so ingenious!
It's a feature in the next version of Safari as well: http://www.flickr.com/photos/wyctim/2568406483/
It's sorta funny because in the past people complained about sites hiding browser chrome and rejoiced when browsers let you disable that Javascript feature; now it's reversed and we're excited to be able to view sites without browser chrome.
