About the only thing I miss is a full keyboard for sms & iMessage. And I have an old Mac Mini laying around that could be put to use if necessary.
A good place to get a basic rundown would be here: https://matrix.org/docs/projects/bridges
For the puppet bridges (which is what I'm running), you can take a look at this repo: https://github.com/matrix-hacks/matrix-puppet-bridge. You're also very welcome to ask around in #matrix-puppet-bridge:matrix.org about getting the bridges set up. We're pretty friendly in general :)
