I love the size and power of my N800 and I still use mine everyday. If I had not dropped it messing up the charge connection it would still suit me perfectly.
I bought a Nook but did not like the wifi connection it gave. It would not stay connected to the internet and I would only be 20 feet from my WiFi Router. I can take my N800 outside on the patio and get perfect reception.
So if you loved your N800 and needed to replace it what would you buy?
