After reading numerous posts/comments, it seems that people who are against iMessage are the ones who don't understand it. What does it do? It's built into your iOS's Messaging app (the same one you already send Texts in). When you go to text someone, iOS 5 will automatically detect if that person is using an iOS 5 device & send it as an iMessage. If they aren't using iOS 5, it just sends it as a Text automatically. The End-user does NOTHING different that what you do today. What are the benefits of iMessage versus just Texting? -iMessages don't count against texting plans -iMessages will tell you if your message is delivered (and Read, which is optional) -There is no character limit, unlike the 160 characters in SMS -iMessages use data (ex. 1KB), so you iMessage people internationally cheaper than SMS -iMessage works on iPod touch, iPad -Group Messaging -iMessage works on Edge & 3G & Wifi (Good for us AT&T users with no reception ) What's the difference between iMessage & WhatsApp or Kik? -To use WhatsApp or Kik, the other user has to have the those Apps. iMessage is built in. -You use one app for SMS/iMessage, versus using WhatsApp and SMS/iMessage -It's free (unlike WhatsApp) -WhatsApp & Kik work on Android/iOS/Other platforms, iMessage is only for iOS 5 Devices -With WhatsApp, you'll have messages scattered across WhatsApp and between your default Messages app. -iMessages works on iPod touch/iPads. WhatsApp does not work on iPod touches/Wifi iPads The Key here is: you do NOTHING different than you're currently doing to send an iMessage/Text; iOS picks the best option (iMessage being the best since all the benefits I listed above). Why wouldn't you use iMessage? -The only reason I can think of is this, you're traveling internationally & data is more expensive than international texting. It makes no sense not to use iMessage. You can still use WhatsApp or Kik for Android/WP7 users but it makes no sense not to take advantage of iMessage too. In summary: Apple automatically sends your texts are iMessages when possible (which is good since it's cheaper & has a lot of benefits.) People will be sending iMessages & not even know it (people who are oblivious that is). Feel free to discuss or point out things I've missed. Thanks.
