If this means bringing to market a new version of the tablet, tailored to a specific carrier's WImax needs (and "maybe with Wifi and/or BT too" :-), and it is still called the N800, then consumer confusion is going to get worse, not better... :-)

OTOH, there are Wifi and BT adapters in SD format, so it's not impossible that at some point Wimax capability could be added to the existing N800 by way of an adapter in the external SD slot...
