Bjorn Kjeldsen, head of LEGO’s Magnetic Research Department, listed several reasons for the shift:
First of all, magnets are much more fun. What child hasn’t spent hours attaching and reattaching piles of magnets? They are much easier for small children to use than the current studded brick. Secondly, people equate magnets with fun and style. Not so with studs. Studs are old-fashioned. They are so 20th century. Magnets will take us through the 21st century and beyond! Lastly, there is the engineering issue. What with the recent decision to transfer production from Mexico to Madagascar, we needed a new brick that required less manufacturing precision. These new magnetic bricks fit the bill perfectly.
I guess this gives a whole new meaning to studless creations…
