I don't know what "titchy" means, but actually, the books in the iPhone's Kindle reader are surprisingly easy to read, even in sunlight, and the form factor of the iPhone is better for reading when in a checkout line, on a bus, whatever than the Kindle. It's very simple to open the book and start reading with one hand, which the Kindle requires just a bit more work. Plus it fits in a pocket vs Kindle doesn't, and did anyone mention it takes phone calls as well? I wouldn't suggest hours and hours of uninterrupted reading on the thing, but for sneaking in a chapter or two - think department store shopping with the wife - it's really not too bad.

I previously owned a Kindle, now own an iPhone and for my purposes, when it comes to reading electronic books, the iPhone wins by a neck. Oh and the books I purchased for my Kindle were waiting for me when I registered my iPhone.
