Today I bought one of those 4-8 Leappad systems for my ds 4th birthday. He loves things with buttons and so I thought it would be right up his street. However, I then went to some other shops to buy books for it to find that nowhere had any apart from ToysRUs. JohnLewis told me LeapPads were being replaced and then I read on the internet about the Tag reading system that is supposedly coming in later in the year www.leapfrogshop.co.uk/leapfrogshop/tag.html . Does anyone know anything more and should I return the LeapPad? What would be a suitable alternative?? I don't want to buy into it if the books suddenly start being hard to find. Many thanks in advance.
