while I generally don’t much care for the formatting, pagination, text sizing options, etc., in the Kindle for PC app, I do like that fact that I can go from one device to another and simply resume reading where I left off on the previous device. I understand it works pretty much that way between the Kindle and other devices as well.
That’s a Good Thing since I tend to have several books “in process” at once, and with eBooks I generally read on more than one PC–my preferred reading device for eBooks, largely because of screen size, greater flexibility in the way the screen displays text, and old eyes.
Having the app keep a thumb in the text, as it were, and open where I last was is nice.
