Hi The way multitasking is done running just key APIs is fine but im sick to death of holding my finger down 3 secs to get the little red button up to close one! for the life of me why did not apple chose to use more screen space for task swithing as the app is useless when you double click the home button anyway! I think it would of been better as verticle list with close spots already at the side and a button to close all tasks for the end of the day! Its a real pig to keep double tapping holding then closeing 1 by 1 and scrolling to find the next! they have all that space to do more like lists or expose!
