Our son uses an iPad and iPod touch, and he does fine with the screen keyboard. The battery life is 10 hours on an iPad, so he doesn't need to plug it in during the school day. We were having issues transferring files from the school computer to the teacher's laptop, so my son now uses his email account to send files from his device to the teacher's laptop. And there are several universal connectors to connect the iPad 2 to VGA, DVI, and USB.
With his dysgraphia and dyslexia, I'm just sorry we waited so long. There are some great educational math games that have already helped him over some barriers he was having.
