Wow - great book! Just finished skimming some parts and reading in depth on others. I'll be coming back to it often I think, it is very helpful to see things from my son's perspective.
I don't have an ereader of any kind, and my eyes are straining after spending all evening on the laptop reading a pdf, so I vote for a hardcopy. I'd buy it!
Although I must admit I will be sending my family the link to the pdf which certainly makes it easy to share.
Personally because my son is diagnosed ASD (classic autism, but high functioning), I prefer a book that deals with ASD rather than Aspergers only. After all, people with Aspergers aren't all the same, and some of them may have more in common with an HFA person than another Aspergers, depending on their particular issues. I am also swayed by something I read in Tony Attwood's book - that after HFA kids get over their language delays, there isn't much to tell them apart from Aspies.
