While that may be a good point, you also need to consider that Gmail is part of Google Apps for Business. I don't really mind the changes for my personal Gmail account since most of the emails that go through there are quite simple and these changes don't have any real impact on my workflow. But for my work account, it's a whole different story. Most of these changes make my experience quite annoying when dealing with business emails where I often need to copy email addresses, modify subjects, CC people, etc.

Breaking Gmail for business users doesn't seem like a good idea since they are the ones who are actually paying for the service.
