Do you have evidence that HTTPS results in user retention problems for gmail? I have heard that it may for search. These are two very different use cases. I can recall users and articles in years past asking for https to be default for gmail. Yes, us geeks knew its been an option for a while. My original post was simply pointing that the decision should be made based on what users want...not as an excuse so the media or Google can publish inflammatory digs in their issues with China.
