This is also true in Google+ and Google Reader. It really throws off my flow. Whenever I try to go back to the main page, I click the logo a few times before I realize it doesn't work anymore...

A few weeks ago, in G+, the logo would give a menu of services, which was also not useful for me.

Maybe they changed this so we get used to using the top navigation bar. Clicking on Gmail on the G+ bar refreshes mail, or sends you to inbox.

Also, in Gmail, one solution to going back is to use the left arrow button to go to inbox.
