I use my e-ink Kindle for reading stories. For technical or reference manuals it is woefully incapable. Screen sizing for 6 or 7" devices probably makes pdf reading difficult even if it's render-able.
The iPad (ie, any 10" tablet) shines for reading content that's best served as a PDF over ebook format (ie, included pictures, possibly video). Interactive content really does require at least a tablet.
