My first ever programming job was a project for Lego and as a bonus they gave my friend and I a Lego Mindstorms set each. This was version 1.5 of the first edition. I remember we installed legOS (now brickOS) which allowed you to run code on the RCX. Definitively gonna buy EV3. Would be fun to try some of the algorithms Sebastian Thrun taught in his Udacity robotics course.
