Hi,
Memory Magic had only been available in PC-CDrom format .
Last time it was 1 CD .Now it has been divided into 2 cdroms and launched few days back named Silly story and super flash and is available in certain stores.I see from MemoryMagic website they still have old version format but the contents are exactly the same.I had been happy with the purchase.

Hi Cassidy,
The children may be uninterested in lesson if they are familiar with it.

This is an indication for us to change lesson.For my daughter with tweedlewink intially I showed her 3 times,but observered she was not not interested all the times and now a days I show like one lesson once in the cycle and will be repeating the cycle once they are overand she is really eager with tweedlewink now.
But I would say there are really Good.Hope your son enjoys them aswell

Can share recommended good books for preschool children .To start ball rolling.

1.The Very Hungry Caterpillar - Eric carle
2.Cat in the Hat - Dr.Seuss
3.Fox in Socks - Dr.Seuss
4.Mr.Men and Little Miss series

Tomy,
 understanding ESP GAMES are to develop some sort intuition in kids.

I remember one of the testimonials read somewhere regd ESP that
"The child was in her room getting ready for bed and her mom came to her room to check when the child told her "Mom you came back home, 10 minutes back in ----- colour dress",Puzzled her mom asked "How do you know?",
The child says " I saw you", Mom asked
"Oh!were you downstairs when I came in?" The child says "No,I can see from here.".

I have been using tweedlewink and wink for couple of months for my 31/2 year old daughter.I would say they are quiet good.It is quiet useful when are too busy to make flashcards and do it for them.This program can be used as home training lessons for shichida .
