I've had an Arduboy for years and while I like it and it's high quality build, there are things that I don't like. One of which is how hard it is to flash new games. I really like the Micro:Bit and all the sensors even the v1 board included and how easy it is to flash. Swapping boards out that can be pre-flashed with games is awesome and the potential for tapping into the extra hardware sensors mean games can be more engaging. I look forward to really playing with it! Shipping was very fast for being nearly on the other side of the planet and the build quality is fantastic.
