@Bill Detwiler: I know it's been awhile since this article was written but a question has arisen that requires your input
Was just wondering if there's any way of confirming from the tear down that this tablet has this functionality?
The reason I ask is that a few of us at XDA developers have noticed that occasionally this tablet exhibits the ability to be able to give this functionality then mysteriously it disappears in an official Sony update are in software that is able to demonstrate it.
In my own case I was unaware that this tablet had such functionality but was pleasantly surprised when I installed "BlueIR" universal remote app. Imagine my surprise when every time I pressed a on-screen remote control button I received a haptic feedback! This functionality also presented itself when I installed another universal remote control app called "Dijit Universal Remote".
However after using these apps for short while to test their suitability for the UK cable market the haptic feedback functionality mysteriously disappeared, even though "BlueIR" universal remote app has a settings functions to actually test and alter the strength of the haptic feedback.
Any hardware confirmation would be useful as you can imagine, regards.
