I like iFlow very much--especially the autoscroll and the history functions.
Two things to remember:
I sometimes don't bother to turn off the display on my iPad, letting it "automatically" turn off after a period of disuse. This doesn't seem to work with iFlow--apparently the automatic shutoff is disabled.
Also, if you are tempted to flip a piece of lint off of your screen, be careful. With the inertial scrolling system, you may wind up several pages away from your reading point.
