I agree it's a gimmick. I've never been fond of touch screens. Human hands are always very dirty/oily. Just look at anyone's iPod or iPad. When the screen is filthy it makes it very difficult to chimp your shot..and especially so with today;s antireflective screen coatings. One smudge and your wanting a cloth and some cleaning fluid.
Where the touch screens are useful is when you can write on the image or manipulate the image in some way using finger gestures...though I am very acclimated to zooming using the other camera controls...and Apple has that patent anyway.
No touch screens on our pro and semi-pro DSLRs please. Save it for the kids to play with.
* Touchscreen - Couldn't be more of a gimmick
My Panasonic G3 has a touch screen and I have found it to be quite a fast way to access camera features. Much better than the quick menu on my T1i. So I would like to see a touch screen on the 7D2.
I still think it's a gimmick. I don't know about those who use or want to use a touch screen on an SLR, but when I'm shooting, I'm holding on to that camera with BOTH hands! Maybe I'm just overly protective of my gear, but you'll rarely find me holding the camera with just one hand with no neck strap. So at that point, I'm pretty much limited to index fingers and thumbs -- which work just fine operating the existing buttons. Throw your commonly used menu items in the custom menu and call it a day. Though I wouldn't mind seeing the ability to add more than six items to the custom menu. But there's a big difference between a magnesium alloy SLR and a five ounce iPhone.
Besides, I'd rather Canon use their resources on developing better imaging technology than waste those resources on a trend that arguably has little to no impact on picture quality.
