Just got myself a new Kindle 3. As an avid reader of novels this unit is incredible. It is funny after years of reading books how, when I get tired and I am reading the Kindle, occasionally I go to the top right corner to turn the page.
I expect in a couple of years when I am fully Kindle-ised I will pick up a paperback and try turning the pages by pressing the sides of the book !!
I have already started using Calibre ( great program ) and have already hacked the Kindle with Jailbreak to get rid of screensavers.
