My understanding is that Phase is much faster but less accurate. Remember, 
Phase uses sensors in the body while Contrast measures off the sensor - it has 
to be more precise but the sensor has to be exposed at the moment of focussing. 
That's why the 4/3rds consortium are so keen to get contrast detect working 
well in an 'SLR'.
