So, what's the big deal?  Another handheld kids game out in time for the holidays.  True enough, but this one is special.  First of all, its street price is around $150 and, for what this is, it's amazing.  Dual screen (one of them touch-screen) and wireless.  Just how cheap can this stuff actually get?  If you believe the guys from Intel - there is no downward limit.  We're going to see much more handheld technology and as the feature sets grow, it is going to change the way we live.  Wi-Fi, Wi-Max and RFID alone have the capacity for monumental change - add some computing horse-power and it's a new ball game.  When we look back on the early days of the transition ... this class of "toy" will be considered a tipping point.
