I don't like haptic feedback- it doesn't seem right sometimes. Maybe if the click sensation is more subtle, but on my bosses Alpine GPS head unit, it feels like my finger is being shocked when I press the screen.
I completely agree. I've used this "haptic" tech before on an Verizon LG Voyager. It just feels like a little zing on your finger when you hit a button. I find it rather annoying actually. Now, I don't believe the LG Voyager implementation could change the vibration depending on the command/button, that would make it slightly more appealing in my mind, but still nothing I miss on my iPod Touch.
Now I'm also not sure this is the same technology as the Voyager, it sounds as if this is more advanced. Honestly, though, I think this vibration-on-touch is a really weak implementation of a haptic system for touch screens. I'm would imagine Apple could and probably will in the future pull off something truly extraordinary in the "haptic-touch" area.
By the way, wasn't there an article on one of the tech sites (or maybe here on MR) about a flat display based haptic technology that replicated the "click" sensation of a plastic button?
