One of the things that really stands out using an iPhone is just how smooth it feels compared to using Android.

How has Apple managed this incredible feat? A better question might be: “How has Google managed to screw up Android’s multitouch so much?” According to Andrew Munn — a software engineering student and ex-Google intern — Android is so messed up that Google might never be able to match an iPhone or iPad’s performance. Ouch!
