My new Tuff-Luv case arrived today, and it is perfect (and beautifully red
)!
The round hole for the action button is large enough, so that I can press on each side of the rectangular button. I can access all the other buttons as well and I am even able to open the loading port cover with the case on.
The cover is easy to hold in one hand, the cover flips all the way back and even locks in place with a magnet. The case has a stand that enables me to place the reader in a good reading position on the table when I'm reading while eating.
All in all, it's all I hoped it to be. Thanks again, everyone!
