The lack of unified SMS integration was a HUGE mistake IMO. As much as these messaging apps want SMS to go away, its not. It is the only common "language" across all devices and providers - not to mention the older generation has no idea WTF all these messaging apps are.

My hope was that Allo was going to fix the disaster of a decision by google to split SMS and Messages apart in Hangouts.

I want one app that supports SMS and messages and I want it web enabled so I can use it from my computer. iMessage has this nailed.

I was a Google Fi customer. Before hangouts separated function I had an awesome cross platform unified messaging experience. I'm switching to iPhone after 7+ yrs on android partially due to this android messaging mess.
