I have a Kindle (2nd edition) and my husband has a Nook. Mine is 3G and his is WiFi only. I can download anywhere (and I DO mean ANYWHERE!) He can only download when we are near WiFi. So, the choice is yours. We travel and some of it is to areas that do not have WiFi capabilities so I can still download but he can't. Go figure! Anyway, we both love our eReaders!
