Chrome 2.0 is ok. Nothing blows my socks off. More like a set of tiny tweaks. The full list is here.
1. An option to control handling of "mailto" tags. For example, invoke Gmail.
2. Right-click on a hyperlink or selecting the address bar content, and have a pop-up option to convert to Tiny URL -> Clipboard.
3. A built-in Google Toolbar, tailored for Chrome (minimalist version)
4. An option to explicitly remove an item from the New Tab page (history suggestion)
