haha, I played go a bunch when it came out and my wife was pregnant, it was a fun excuse to walk around outside and you learn a lot about the local neighborhood history etc.
I have a cheap Velcro phone holder, I think it cost $3. I would swap it to my moped or bicycle, whichever I was riding that day, and there were a few stops i'd pull over, toss a ball or load up from a stop, then cruise on. definitely not watching it while riding tho. but I could just stop, swipe, go.
the ram ones look sweet. I've been good nuf with mine tho
