Been using both my Forma, and my newer PW4 case-less, and loving the super lightweight reading experience. To make the PW4, and also my Nexus 7 tablet, a bit easier to hold onto one-handed during lengthy reading sessions, I bought a little hand strap that's designed for Ipads or smaller tablets. On the Nexus I hook it on vertically on the back. On the PW4, I hook it diagonally, and it's just right, gives just enough tension to hold it comfortably over your fingers.
