The DX is the most addictive thing I've ever tried. The DX vs K2 thread has more. I hav never tried crack but I suppose they have similar effects. My spouse calls it my girlfriend. My spending on books has gone down and the confort of travel is great. I don't think a color screen will help (iPad, Sony, Nook) because of the battery life question and, anyway, the books I read aren't in color. the browser is awful, but it even works, though labeled "experimental". I don;t use it anyway. BTW, I travel internationally a lot but I would not get the international version. Just download to a computer and xfer to Kindle via USB.
