Hi,
I have an iPod Touch, but I prefer to read on my Cybook. I had a look at the description of the "features", the tilt-scrolling sounds neat, but not enough to trade my large comfortable e-ink screen for a tiny backlit iPod. The other extras (audio and video) I'm not interested in at all, but I suppose others might be. I might buy this e-book if it's not available elsewhere, but I had never heard of this author before, so this would not be a priority buy for me.
That's my feedback, for what it's worth. I don't think I belong to your target audience
