Serves the same purpose as well since unprotected the touchpads can get damaged. I should know because on my deck they were turning a tiny bit shiny. So I put some stickers on my trackpads there to prevent them from being permanently disfigured.
yes there are and yes they do! actually that's the sole reason I decided to get textured vinyl instead of smooth, I like the touchpads being a bit textured.
I have the same textured skin minus the colours. Absolutely love my steam controller and use it almost every day. Got my configuration all set up for Monster Hunter Wilds on Friday!
