Then of course, there are people in denial who refuse to accept there are any faulty devices at all! Maybe you're one of the 'lucky ones'. Ignorance is bliss.
The problem is is that reading is such an intimate activity, you're enjoying words for the sake of them, and as such they really should be displayed properly in all of their literary glory . The intimacy of being absorbed in a good book is cheapened for people who've spent 500 bucks on a device promising to be the pinnacle of e-reading only to have the colour of the background change to its primary opposite with every word. And having weird splotches on the side of every book you read, forever. If I was watching Keeping up with the Kardashians or stalking my exes on Facebook it probably wouldn't matter to me as much, if at all. Problem is is that I'm very easily distracted when I'm reading a book, I need the experience to be seamless otherwise it lessens my enjoyment. Same with watching a movie, listening to music, anything that requires me to be engaged properly. It's a psychological concept called 'flow', where all the elements of an activity come together in a way that inspires you.
It's like enjoying your favourite bass riff on a pair of tinny computer speakers - it just leaves you disappointed and angry more than anything. You'd be better off just not listening to the song at all. Or enjoying the best steak in the world with a cheap, sour wine. Take another swig when someone rolls their eyes at you for being too fussy

. Stay positive peeps!
