I give my candidates a choice of a whiteboard or a laptop and projector. Most people choose the whiteboard. Some outright say that they need to look at it at home. The latter will not be able to participate in a meaningful way in a team, and as much as I want to, I don't have work for a loner. But my point is that, as a team you need to be able to express ideas in a format that other developers can reason with you in a live setting. Nothing beats a whiteboard in that regard. You can use a projector and a computer, but what if you need to draw a graph or something else? It's not a tall order to ask them to be able to do this. And please don't forget that I'm not asking people to implement RB search trees, but usually a simple loop and an if statement. Reverse a list using a for loop, transform this string into a palindrome, is this string a palindrone, remove all duplicates in a list - stuff like that.
