What happened to the Technics series of Legos?  Yes, they are still around, but in the late 1990s Lego decided to start combining parts to make assembly easier, and I would also assume, to cut production costs.  Well thank you, you have lost a customer.  I liked the Technics because it was logical, and mathematical, and made you think.  Why not just get rid of all the series and make only Duplo?
