Actually iPad also lag lar... it's just less... and also cos the way the iPad is set up where multitasking is concerned, it allows less memory to be used up and hence it always seems smoother... there are trade offs... just that most Apple users don't see what they're trading the smoother interface for... since it doesn't affect them, of course it's also moot... but users who value the flexibility of the Android system, then it matters... you can have very smooth user interface on Android if you restrict what your tablet can do, including keeping apps in memory etc... but that's not what I want... or many Android users may want... so different strokes for different folks lar...
