Wimax phones
Nokia has announced thier new wimax enabled phone which will be launched some time next year in the first three months and Motorola is working on thier version of wimax phones as well so it will be interesting to see both the new wimax phones.
The reason I am so excited about wimax phones is that I would like to use wimax internet connection to make voip calls on the move 
I dont see any reason why this cannot be achieved with good results as the trials have shown that connection doesnt drop while moving although the speeds come down but it would stil be enough to carry packets required for voip.
