I'm kinda shocked at the discourse of touch screens. Go into your cell phone for a second and scroll through the photos, check focus, share the photo..... Well, the camera should be that easy with a touch screen. As of now, it can use a ton of improvement.
BTW, touch to AF+ shoot is just one setting. You can touch to AF, touch to AF zone, touch to AF point, hell, with proper implementation, touch to preview, the possibilities are many.
The Sony remote app, you can touch to AF spot from the phone.... Why not straight from camera? The tech is already here, and been around for ages.
