The web already has four "major" browsers firefox, IE, safari and opera. Do we really need a new browser?
Most of these browsers have a history and evolution associated with them, which prevents adding cool new features ( e.g. each tab as a separate process ) is not possible without a major code rewrite/redesign
Moreover, do we really need yet another partial implementation of the web standards?
I for one, do not want to code and test for another browser.
They are using WebKit, so it's not adding to the confusion
Not to mention that by using google's browser, you will give them unadulterated access to your every movement on the web.
It is open source, so the possibility of them adding any sort of google specific tracking is close to zero ( or else it would get forked ).
Many people write memos to tell you they have nothing to say.
