So I had my first "read" with the KDXG. Im in love. I feel bad, because I love my 505 too... my love affair with reading was rekindled (no pun intended) with the 505, and I feel like a rich husband leaving his long time relationship for a trophy wife.
But damn, everything about the KDXG is wonderful. Its the perfect size, the perfect weight, the perfect screen. I cannot say enough good things about this reading machine.
