1 DVLUP
One of my favourite parts of being a developer is the DVLUP portal and network. Essentially it is a gamification initiative to provide encouragement and incentive to developers to build and enhance apps with specific features. As a developer you earn experience points (XP), which you can then trade in for really cool stuff like device, earphones or design reviews and licenses for tools. It really gives you an extra push to get your apps done by a certain date to get that Lumia 1020 or an hour in the hands of a designer that can help you get the right workflow and layout.
DVLUP is free to join and fully integrates with your Microsoft account as well.
