Is the touchpad going to be a good alternative to a scroll wheel? My NVidea Shield remotes use a touchpad for the volume, and it's "just okay." Every time I adjust the volume on my TV it feels like I'm doing something naughty to the remote.
I really like the mice that have a clutch button that lets you unlock the wheel for free scrolling. It helps for scrolling through long documents. I feel like a touchpad scroll wheel doesn't really change the finger motions. Unless, they do something clever like where you drag your finger down and hold it at the bottom for constant autoscrolling. They could adjust the speed of the autoscroll based on how fast your finger moved.
I wouldn’t want to be without a notched scroll wheel (for discrete scrolling steps), something which can’t be replicated by a touchpad.
Also, the rocking motion and cogwheel-like touch of the finger on a scroll wheel feels nicer and more controlled to me than the sliding motion and friction on a touchpad.
