Especially the wifi version.
I would be interested in this as well.
I haven't yet but I found a really good deal on a WiFi Nook and will be testing it probably later this week when it arrives. I'll try to remember to post back...if not, reply to this thread again and I'll get an email which will remind me. FWIW you might check rewards options via your credit card and could get maybe 5-10% off or so on one.
Library.logos.com works...but is kind of painful due to the refresh rate on the e Ink screen. I can live w/ the refresh rate when 'turning pages' in the main app, but the web browser gets frustrating very quickly. I actually use the LCD screen at the bottom to quickly check RSS feeds because it's so much faster. I don't see getting rid of my iPod touch for web stuff and basic reading, but the Nook screen is very nice for extended reading.
