I haven't done much WiMAX stuff. The only one I follow is DVW - which is COVAD. They are just starting with WiMax as their primary function has been DSL. I think it's a good buy .90 area and should double or be taken over as they have a national network.
What are the WiMax stocks you follow?
RFID is interesting but so far none of the micros have done much. I followed DPAC for awhile but they can't seem to get their act together. I didn't like the way they treated shareholders in the past.
