I have a real hatred for the merging of Google services - and I'm not even sure why. I think it's because it just feels like the erosion of my privacy. I've become someone that uses multiple browsers. I'm logging in and out of services - just because I want to shed my persistent identity - that I probably have exposed anyway.
Not having to sign into different services with different credentials is one of the only benefits I feel I get, and yet I'm doing more logging in and out then I ever did before.
