I'm not sure if my hissys are (ooo neat, modest just died inside, anyway) the same as everyone else's... but my thingy always hiss'es for a second or two when contact is made on the touchscreen. It's always done this, but you don't hear it unless your ear is to the speaker. Reminds me of the sound an audio cassette player makes when you hit play. Wow, no double keypresses; Diablo is coool. <grin>
