First off, the first thing you notice with the Kindle is just how nice the screen is. Amazon designed the kindle so that it would disappear in your hands as you are readying and that is certainly true. The screen is clear, crisp, and renders detail in photos exceptionally well considering it only has 16 shades of gray to work with.
Whisper net seems to deliver books as fast as I would expect it to, purchasing a book from amazon.com on my computer, then turning to my kindle a few minutes later and the book was showing in my list already. Wireless delivery is very handy as I don’t have to search for the USB cable and copy the books manually.
Starting with Version 2.3, the Kindle now supports native PDF reading without the need to convert. There is a catch however, and that is you cannot zoom the text. Most of the PDF files that I read are formatted to fit an 8.5×11″ sheet of paper, not a 6″ screen. You can rotate the PDF and hold your Kindle horizontally, but this only goes so far, as some PDF authors seem to be using 6 and 8 point font as standard text. The solution is to use an application such as “Calibre” (http://calibre-ebook.com/) which is free. Once I converted my PDF files to .mobi, I can zoom the text and read them comfortably.
