To me, this announcement feels pre-mature, the software doesn't seem ready until it integrates with other clients. But I think, giving time, your concerns could be addressed: -Integration with other devices, backing up and importing your back up between devices, are features that will come, eventually. -There are several 3rd party standalone desktop apps being developed for Signal. -You could maybe build a Textsecure server, and in the future, who knows, there may be documentation for doing so. Maybe Signal isn't ready for you right now now but I wouldn't count it out!
