N8x0 is either the N810 or N810 Wimax or N800 devices...all can run the same operating systems and utilize the same software... NIT nokia internet tablet...precursors to the n900 and the new upcoming neo900 .... Proper little hackable computers.... ...you can have telephony...skype...gtalk...gvid talk....but it isn't a phone...no cdma, gsm or lte ....essentially. Used to be a pretty penny.......alot of fun ...and now you can find 'em dirt cheap...good introduction to maemo...and a cheaper way for some to fiddle with multiple operating systems.
