My sister in law is an iPhone user. She immediately tried to pinch and swipe the screen to get around. Sorry. Kindle is just not that kind of a device. You have to use the 5-way pointer or the next/prev buttons although there are some neat shortcuts. I quickly found the device easy to read and use. I installed Calibre a neato free opensource ebook manager (lucky for you, it works with Linux and Windows and supports many ebook device types including the Kindle). I use it to convert my existing documents to ebook format or to download newspaper versions automatically off the web. Yay.
Other favorite features: It will read text to you in male or female voice or can play background music while you read .. and it fits nicely into my suit coat jacket pocket.
