I have a question for those of you that owned both the K1 and the K2. I have my K1 in my Oberon w/corners cover and slip it in the outside pocket of my purse. I guess when I bump the it against something (usually me) if it is in sleep mode it wakes it up and then starts turning pages. When I open it up I have lost my place in my book. Very annoying. I prefer to leave it in sleep mode rather than turning it off when traveling. My question is, do any of you have the same problem? If so, does it do it on the K2 as well?
