Thank you all for your help, it is very much appreciated.
I will put up a link to the results of this survey (on this thread) in a week or two (and my research if anyone is interested, when its finished).
I am a real eBook fan and the reason I decided to research this subject is because I think that although there is a real boom in eBook sales ATM, there will always be a place for conventional books. I for one find it hard to follow study guides online and opt for printed material instead.
I will also be considering the effects of the digital divide and how it impacts upon our reading habits.
I was hoping that asking quests about age/gender might suggest that eBooks attract a niche market. We'll see...
Apologies for the issue with one of the questions. Looked at the survey and think it may be a glitch with the program.
