Increase the timeout then. You're probably already in the habit of manually turning off the screen when you're done with the device, so why do you need it to turn off automatically after a minute or two of inactivity? Especially when modern tablets have battery life measured in many hours of time with the screen turned on, does it really matter if you do happen to forget and it takes five or ten minutes for it to correct your mistake? And if it really takes you more than 10 minutes to read a page on a tablet screen before you touch it again to flip the page, just turn off the timeout altogether.
