The main appeal of it to me was always quick reply. I downloaded it, tried it for a little bit...at first I liked the convenience of quick reply but soon realized that it was useless because I would almost always end up going back and forth for more than just one text. Quickreply is only useful for one-time texts, ie. "sounds good", "I'll be there" or "call you in 10". It is useless for back and forth conversations as you have to keep deviating from what you're doing and it's far easier just to hit the banner and switch to the full screen conversation. Aside from that the other benefits seemed negligible, I quickly uninstalled it. I'd rather have to original stock look and feel of the Messages app than those small benefits I had no use for. What do people love so much about it?
