First off, the ui is incredibly inefficient for dealing with large volumes of email. I haven't found a way to choose which header columns to display (and in what order), resulting in only partial display of critical information like From and Subject. Secondly, there is no easy way to select multiple, particular items for deletion. I can select all, but that isn't very helpful if there are actually some items you want to read amongst that sea of spam. How about a simple checkbox next to each message, like webmail has been doing for years and years. When I do click the delete/trash button I get a prompt about deleting it from just the device or from the server as well. If I select server as well, it connects right then and there to do it. Having to go through this process for multiple messages is quite simply a pain that has made the 770 useless to me as a mobile email platform.
