Well I hope the demand is high. I do see a lot of people in the Kindle forums asking "are there any textbooks available on the Kindle?" When I first joined the forum, prior to even owning the Kindle, I asked the same thing but was a bit more specific and referenced C# books and a lot of people repsonded saying they already had downloaded a bunch so I bought the Kindle solely for that reason. Also, my nepehew is a teacher and he told me Northern Arizona University is conscidering getting many of their textbooks converted and maybe offering Kindle versions for the curriculum. I dont know how many of them are WROX books but that was good news. All I can say is I will be a good customer! :)
