I use my Kindle to read all sorts of non-fiction works (I very rarely read novels). I'm not sure why everyone assumes it's only fiction readers that would care- there are plenty of non-fiction books that aren't reference books. I find it much preferable to read over the iPad, for all the standard reasons (glare, eye strain, etc.) I also find highlighting to be much preferable on the Kindle (maybe Amazon has updated their iPad app, but the version I have won't let you highlight across page boundaries) as well as going to footnotes and back. Of course I do a lot of my Kindle reading outside (at the pool, at the park, whatever) so that plays a major factor as well, it's like I don't want to use my iPad unless it's dark (this applies to more than just reading) because I hate seeing reflections. The only times I really use the iPad in place of the Kindle is when I'm in a dark place (I've used it quite a bit outside at the hot tub at night), and I use the iPad for Instapaper usually instead of the Kindle. Another reason I prefer longer reading (which Instapaper doesn't really fall under, while articles are usually longer form it's not like it's a book) on the Kindle is because with the iPad I find that I'll be too easily tempted to press Home and mess around with something else (I realize this is my own fault and not necessarily a fault of the iPad, but it's something that I'm sure other dual-owners have experienced).
