Thanks, Harry. It does certainly have a lot more features than the 505. Personally, I wouldn't need any of them, but I'm sure a lot of folks would.
I suppose I'd really like to see a whole bunch of e-book readers side by side. I've only seen my 505 and one older Kindle. I had never seen any before I received my Sony. I ordered it because of information I got here in MobileRead at the time. It would be great the have a 'hands on' side-by-side exploration of the devices. I wonder if there is anywhere that this sort of thing might be possible? I would find that a justifiable excuse to travel abroad!

I don't know if my wife would find it just as justifiable, but she's a good egg. She'd go along with the idea!
