That's a genuine question, the only thing I can think of is the 'Apps' dashboard with a link to the Chrome Web Store, apart from that Chrome seems to consist of just the essential elements of a browser.
Some of the newer WebKit features are getting bloated as well, and are built-in even if you don't need them - e.g. the new Javascript de-obsfucation feature in the developer tools.
Helen: Think of the parents!
The word 'bloated' can be overused, but let's ignore the choice of word the GP used. The fact is, Chrome downloads have been getting bigger and bigger (there was an article here on HN a while back with some numbers), which isn't surprising because a lot more is being included. For example,
* Flash
* PDF viewer
* Developer tools suite
* Chrome-specific technologies like NaCl
* Chrome Store support
* Proposed web standards like Web Audio API and WebSQL (which are significantly more complex and large in comparison to alternative proposed standards to them) and SPDY
Now, the significant increase in size might be justified in some people's opinion, it's debatable of course.
