Key words on this review are fairly "responsive" and "delay". I don't understand why they switched. Leaving behind the IR-based touch interface of the previous Kindle Touch, the Paperwhite sports a capacitive touch screen with two-finger multitouch support. The display proved fairly responsive: When we pinched-to-zoom (which enlarges the font size), there was a second delay between the pop-up window of font sizes appearing and the font actually changing. It then took another second for the pop-up to disappear.. IMHO, that delay would drive me nuts !
