If Apple users prefer the Kindle (and I'm not convinced of that relationship), perhaps linux geeks prefer the iLiad. I love mine, anyway.
I think the Kindle is still priced too high for the typical reader (in developed countries, to say nothing of lower income markets). I know that's the cost of the components, but it's just too much for most people to pay for a single-function device-- even if it does include live access to Wikipedia. But I'm glad Amazon got into the market, just for the increase in visibility that this has given to eBooks.
What I'd like to see next: a deal with Powell's, or any other large pbook/ebook seller to promote a competing lower-cost less-restrictive reader/content combo. And I'm still hoping to see "book club" businesses hop onto the ebook train.
