This app makes writing long and/or complicated text messages much easier and faster. I like how I can lookup my iPhone contacts from my computer, select and dial or text quickly. Its a nuisance that I have to press send on the iPhone for texts, but I think this is a limitation of the iPhone. Copying notes & photos from my PC is a breeze (no cables or iTunes) and I can quickly copy from the iPhone as well, which I found very helpful when I wanted to add a photo to an email I was sending. It is easy to use. I highly recommend it to anyone that spends time on their Windows PC, and wants an efficient way to send text messages, dial and transfer information between their PC and iPhone.
