True, uh what what Martin, what excites you most about developing for Android? Oh, a lot of things. Just developing for mobile in general is just the instant gratification of making something and seeing people use it. For Android especially, it's just a huge user base. Everybody gets to use it and you know, it sometimes I scream and curse at the problems of the different device sizes and things like that, but once you get it working, it's just good fun. And you can make so many different things as well. I mean, I worked at one point on an app which used custom Arduino bracelets and we transferred data from the phone from Android to iOS and from iOS to Android phones. It was a conference app, so you'd shake hands and it would detect the movement and zap the thing. That's cool, Ross. That's very cool. And those kinds of things are just great to do. So, I love doing that. I love Android. It's getting it now. It has great animation support and you can do lots of lovely things with it. And I just like I prefer much prefer working here with Java over Objective-C, angry. And of course, now Nathan's going to Swift, but not everything is Swift yet. When does that happen? I mean, I've heard a little bit about that, but it's happening right now. The transition is we've already got a lot of production stuff in Swift only. I have the problem that I started at this job as the Android developer and everything was written in Objective-C, the Apple stuff. So, I had to learn that. And then, you know, our team grew and grew. So, I took on more responsibility there and I never had a chance to learn...
