I'm a big fan of Lonely Planet and have used several of their guides, mostly in the Kindle format. I must say, LP has been very inconsistent in how they've ported their books to the Kindle platform. The big difference is the TOC and linking. In South America on a shoestring, the content was broken up and linked better. I could swipe to move between chapters on individual locations. In this book, a swipe takes me to an entirely different country. There's nothing dividing up the content within those chapters outside of the TOC at the beginning of the country chapter or a couple of links in the introductory pages for each country.
Worse, there are a great deal of sites that are invisible from the TOC. These might be secondary sites or day trips from major cities (chapters). The only way to find these is to read through the entire chapter for a city, page by page. And the only way to find them again is to highlight or bookmark those pages. So, basically I end up creating my own index for the content, scouring each linked section page by page, highlighting interesting points so I can find them again later.
And for big chapters, let's say "Krakov," if I want to find just the transportation section one more time, quickly. Unless I've had the foresight to anticipate this, I'm either paging ONE by ONE through all of the Krakov section or going to the Poland main page, clicking the chapter after Krakov, then paging backward, searching for what I want and hoping there aren't too many side-trips from Krakov. That's completely weak. Aren't drop downs a possibility on this platform? Is a bigger TOC for each of the countries all that hard?
I don't know if this is a Kindle thing or a Lonely Planet thing. But the usability of this material has a long, long way to go. You can do better.
OH, finally, whose idea was it to make the key features, like museums and viewpoints, SMALL and GRAY text next to normal, black text. Seriously. It doesn't make it more readable. Less. I'm reading...squinting. Reading...squinting. Come on.
