Evlengr, I thought exactly like you... you shouldn't have to learn how to drive a $50-60K car.
It was a major concern of mine BEFORE I bought my X3. I found an online vendor which sold a remapped electronic throttle so I figured I could work around the BMW design fault. There was never anything wrong with the transmission on the 2nd gen X3.
By the time my car was manufactured and delivered BMW had fixed the electronic fault and my car exhibits zero throttle lag.
That said, the car will be somewhat reluctant to go to WOT when in ecopro mode.
