I just picked up a Sony 900 from Best Buy in Atlanta about an hour ago.
After loading an ebook I had already purchased on it, I have to say I am a little disappointed at the contrast on the screen. I don't know if it's because I haven't charged the battery yet (it was plugged in as I was reading) but, looking at a book under the same light, I think the contrast leave a lot to be desired. Is there a contrast setting?

I am taking it on a business trip this week and I'll bring it along for the flights. Right now, the contrast is the only thing that is bugging me.
Otherwise, I am pretty impressed at the build quality. Though, it is Sony and they have always built quality products.
I took a 14 day trial subscription to the NY Times. I will see how it is to have it delivered every morning. However, I doubt I'll keep it. With my schedule, I rarely find time to read the paper. I'm more a book person so the NY Times Book Review tomorrow should be interesting to read.
It came with a nice charger which, since I hear the battery lasts so long, I will probably just leave at home and use it to charge on the weekends, if needed. I'll take the USB cable along with me.
The reader also came with a very nice Case Logic hard shell case. I don't imagine I'll be heading to a war zone anytime soon but it's nice to know I'm covered.
I will update this over the course of the week as I get to use it more.
