What is Chrome?

Chrome is still only for Windows. Mac users might try Bootcamp or one of the virtualization products. Linux uses can try Wine version 1.1.4 or later (wine --version). 

 wine "$HOME/.wine/drive_c/windows/profiles/$USER/Local Settings/Application Data/Google/Chrome/Application/chrome.exe" 
 --new-http --in-process-plugins


Both Chrome and Safari are built using the “Webkit” browser rendering engine. If you find a problem in both Chrome and Safari, Webkit may be the problem.

Google has promised an extensions framework; meanwhile there are Chrome bookmarklets
