1) If you have a serial tower, there is no reason I can think of to purchase the USB tower. If you use a USB tower, then you will need the USB support that Robolab 2.5 provides. 2) The hardware differences between the 1.0, 1.5, and 2.0 bricks are (...)

I suspect this is due to the fact that the first sample from the sensor is actually being obtained while the sensor's reservoir capacitor is still charging.
