assistant
on my windows phone , yep, I said it, windows phone :-) cortana was superb, she recognized you had a bluetooth in and ask if you wanted her to read a message, then ignored or read it after listening to your response. you could also promp her to send a message, she prompted you for the recipient then prompted you for the message, then read the message BACK to you and asked if you wanted to change it, send it, you could tell her to cancel at any time during the process. I have not found that combo (assistant, text, phone) on the droid system that works nearly as efficiently as cortana on windows mobile. Your text service is wonderful but we always want more, don't we? I would happily pay more for an app that worked as cortana did. I miss that feature, it was enormously helpful when hands were busy.
