I very much appreciated the Autocast option presented on page 15. I do find myself frequently receiving multiples of the same question and the autocast option through labs would allow me to create canned responses to similar questions. I could then personalize them a little bit. Also, I like the option to undo a sent email. Sometimes, when in a rush, I accidentally hit send and then want to retract the message. I didn't know that this option existed in gmail. Finally, I like the tasks option. I had previously used sticky notes in office and this task piece will be extremely helpful in checking off daily lists which can be seen on any device through Google.
