Sure I would. Don't get me wrong, I love my Paperwhite, but I still love my K3 too. I have read on a non light kindle for 4 years before the PW came along. Only times it has been a bit harder was at night in bed, even with a nightlamp.
But reading in daytime, outside, balcony etc, I wouldn't need the light. I like a lot of things about my PW, not just the light though.
If my K3 dies, I will get a basic kindle to replace it. Even if I use mostly the PW.
