Protecting your privacy isn’t the only reason not to install Google Chrome:
Short story: Google Chrome installs something called Keystone on your computer, which nefariously hides itself from Activity Monitor[1] and makes your whole computer slow even when Chrome isn’t running. Deleting Chrome and Keystone makes your computer way, way faster, all the time. Click here for instructions.
Long story: I noticed my brand new 16″ MacBook Pro started acting sluggishly doing even trivial things like scrolling. Activity Monitor showed *nothing* from Google using the CPU, but WindowServer was taking ~80%, which is abnormally high (it should use <10% normally).
Big, big props to Loren Brichter for making this website and thoroughly documenting this issue.
Loren is a former Apple employee who created Tweetie and Letterpress earlier this century. There is a Wikipedia entry with more information about him, written from somewhat of a fan perspective.
