I admit this is nitpicky, that language is naturally evolving and corporations cannot make rules about how English should be spoken but "Legos" isn't strictly correct. The correct term, per The LEGO Group should be "LEGO bricks". At one point they had this written on their website:

"Please always refer to our products as “LEGO bricks or toys” and not “LEGOS.” By doing so, you will be helping to protect and preserve a brand of which we are very proud, and that stands for quality the world over"

Also, though "Legos" is somewhat common in North America, it's less common in the rest of the English-speaking world.
