I found a lot of improvements in Sense UI. The first things I found, the email client got a new interface. You can choose to view the email grouped by conversations, rather than the traditional inbox. That makes more "Sense"! Because in the most of cases, I was dealing with a few issues at the same time. So, a lot of replies back and forward. Without the "Conversations" mode, I will lose the track of discussions! Yes, that is the reason I love Gmail a lot. Now I can use it in my Android Phone Email client too!
