have posted below for some ideas (as I have some money to spend on DD with severe s&l disorder/delay). quite like the music therapy and the touch screen PC ideas.
was looking online last night and got lost on the world of PCs... I am not very clued up about these things (my mobile doesn't even have a camera iyswim 
).
checked the ipad and find the price rather 
.
stumbled also across the ipod touch which would be much more affordable but the screen is much smaller. how much of a disadvantage would that be? are there other downsides?
also came across various other tablet PCs which are much cheaper than the apple products but surely there must be a catch somewhere. but where??? 
would be very grateful if somebody could shed some light on these things for me.
thanks!
