Just watched DCR. So - let's imagine they fix all the snagging issues. What's great about it?
Battery life? That was a real problem 10+ years ago, but not so much now. Provided that it lasts for 12-24 hrs that's 99% of cyclists sorted. Most people will be going to be having a sleep near a mains outlet. Yes extreme adventurers, tourers and hardcore audaxers may need super battery but I don't think there are enough of them to make it a killer feature.
Simple friendly interface? Ray hates that wheel thingy, but let's say he's wrong and it's actually great. They'll have to go some to beat Wahoo, and even Garmin are getting their act together. Kinda.
Really new features? There aren't any
So if they fix all that stuff they'll end up with a decent enough GPS with a battery life much bigger than most people need ever, and bigger than anyone needs most of the time.
Nice, but not a game changer.
