I got it I got! Man I love it.
I spend a night with my DX, it's so much better than my old beloved Sony 505.
I know the pdf rendering isn't perfect, but it's so cool I can finally read full pages in acceptable font size. I hope Amazon will roll out their new firmware soon to make pdf even better.
I also got e-coupon to save $40 for my second DX, well, I won't be able to afford another any time soon
so if someone wants it, I'd be happy to pass it to you, PM me.
Happy and sleepless!
