I totally agree. The other day, subject line and e-mail address input field would not take text input straight from my keyboard. I had to copy/paste them from a notepad file, and strangely Ctrl-C/V would not work...rather I had to paste through right click menu. Such an annoyance to find the contact and then paste it. I am on a job hunting spree, and this single thing just put me over the top. Furthermore, I wanted to attach some images, so i dragged and dropped them, like I would do previously, but instead they were coming out as inline images. I could not find what I was doing wrong, so had to do it through the "attach images" icon.
I hate the +You thing too, I do not have a G+ account, but still that thing is there. Always. In the corner. Enticing me. Chastising me.
I used to use Google scholar frequently, but since they have removed this option from the tab bars, I seem to have removed it from my work flow. Another annoying thing is, the two similar bar options when on Google search page.
I am in process on moving to outlook.com...simply because I think MS is an enterprise company and more conservative of design changes. Otherwise, I would have to move to a desktop based client.
When I moved to gmail from Yahoo, it was such a bliss....it has been a bliss until some year ago. But I think, I should be more open with my choices now.
