Owning a Transformer Prime or Motorola XOOM has an added benefit over most other devices at this time thanks to their Ice Cream Sandwich updates. In version Android 4.0.3, a slightly new version of Gmail is introduced that includes an “Experiments” section. In this special section, you will find two new options that make the Gmail experience much more well-rounded: full text search and the ability to drag and drop contact “chips.”
The first option allows you to index messages so that they can be searched locally. The second turns the contact “chips” into movable objects. Now, when you long press on a newly added contact into To/Cc/Bcc, you can long-press to then drag and drop them into another field. In the 4.0.2 version of Gmail, a long press gets you into a “copy email” box.
Neat, right? [insert generalized fragmentation remark]
