You've probably heard of the pebble watches. They were the first smartwatch, and they raised a record 4.7 billion on kickstarter in just a week. They have great battery life, a neat OS, and no affiliation with Apple or Google (not to say that those companies aren't making great products, but it's nice to see products that /aren't/ from them).
Here's something else that I haven't heard many people talking about: It's really, really easy to develop for them. At pebble.com, you can just click the develop button in the upper right corner, read a brief tutorial in C, and get to coding your own watchface. In an online compiler. That you can access from anywhere.
Features like this are great in the revolution of open-source and easy accessibility. Rather than download a complicated APK and spend years learning a programming language, we can code a simple application on a web browser, publish it instantly, and make our code accessible to anyone who looks.
If more companies follow their lead to make app development open-source, we will further our ability as a whole to make great products. When the resources are at the fingertips of each and every developer, each high-school programming student, creativity will prosper.
