oh boy, i try again....
there is few different types of resistive touchscreens, n900 (as mikec said) uses haptic type, such touchscreen acts bit different then other resistive touchscreens, let me quote here something from n900 official features list: "The resistive touch screen includes haptic feedback so you know when you've pressed a key or onscreen menu"

so i recommend you read up about touchscreens variants before you post more nonsense.
