Hi, RonF. I've read that if you keep folding the cover back enough, it will soon bend back easily but I myself prefer to hold it like a book.
Regarding the Mighty Bright lights, I have the Travelflex and the Xtraflex2. The Travelflex lights up the 300 screen well enough and I prefer this to the Xtraflex2. The Xtraflex2 seems too heavy for the cover and I find that if I clip the Xtraflex2 to the cover, the cover will bend back a little. I also don't like the shape of the Xtraflex2's clip -- when clipped to the 300 cover, the cover doesn't stay flat, but curves slightly. If I have time I'll take pictures later to show you
