With advice like that the poor chap is going to be perplexed when the book arrives.

For one thing, they will only read half the story if they don't realize that pbooks use both sides of the screen. Turning the page is quite difficult too. Tapping the page simply does not work, and the swipe gesture requires both more pressure and articulation.

The other thing is that a lot of features are actually add-ons, some of which can be quite expensive. Even basic things like bookmarks have to be bought separately. Ensure that you have a bookmark before opening a pbook for the first time, otherwise you'll have to remember the memory location where you left off the next time you sit down to read!
