I'm actually hoping this will be wired. I have a Microsoft Surface Dial that I currently use wireless for various apps and its mostly great. My main complaint is that every so often its a ***** to get it to "wake up" and do its job. It'll go into a power save state and either I have to try commands two or three times initially to get it going again, or I'm forced to alt tab out to the thing I want to do and mess with controls to get it back.
Once its going, its not a problem, but I'd rather not deal with the song and dance at all. Just give me a cable so I can be done with it.
So, again. Hoping for wired connectivity. I'll def buy in.
