Preschool Prep?

http://www.preschoolprepco.com/h/i/index.php

There are now teaching tools to prepare kids for preschool? What do you need to know to be adequately prepared for PREschool? I don't even think learning much beyond adequate social skills seems important for IN preschool, honestly. Learning letters, numbers, that's also nice, for sure. Kids are supposed to PLAY--not spell play--when they are that little. Just sayin'.

I think I will be skipping this one for my 2 yr old, thanks.
