I have never been so frustrated with a UI redesign as I have been with Gmail and Analytics. Unfortunately, I was already using all of the settings pointed out in this post, and I still can't get comfortable with the new design. I can't separate how much of that frustration comes from the large degree of change and how much comes from my long history of use, but the frustration is huge.
I know that many Google employees were similarly frustrated when they were eating their dog food last august. Yet the new look was rolled out anyway.
So I can only assume that the company had solid UI data showing that their target group of users prefer the new design. And I can therefore only assume that the target group of users does not include users like me.
Consequently, there is an opportunity here for somebody to do email right for the people frustrated by the new gmail redesign. I would happily pay for an email interface that makes sense and doesn't change against my wishes... especially if it doesn't require switching to microsoft.
Until then, I will be very grateful to the person who pointed out the 'slow-connection' interface is still available.
