I'm no Apple fanboy or anything, but I always notice that Apple products like the iPod, the iPhone and iPad always have very smooth zoom-in and zoom-out on let's say, images, websites, and every competitor product I see has VERY laggy movements. I don't understand this. Shouldn't this be easy to fix? Even the PlayBook, it's laggy when you get on-screen movements. I don't mean video, just the onscreen movements from the actual OS. Could someone explain to me why this happens? Something in the OS? What?
