It's nice that we can start building with the SDK, but I'm more interesting in experiencing what I've made. I'd rather have the device and build a simple hello world demo that inspires me to build more vs spend a bunch of time diving deep into an sdk and while having no idea how the end user will experience the stuff I create. With iOS for example, you could develop a majority of apps by just using the simulator, since the experience is (mostly) 2d. But I remember when starting out, the more fun projects to work on were using the accelerometer. The only way to experience the magic in that case, was with an actual device. With Magic Leap, the entire experience is spatial. So it's probably the other way around where the device is mostly the only way to really understand what it is that you're building.
