I'm surprised that everyone is going for expensive bike computers these days. Am I the only one who simply uses Google Maps on their phone for navigation?
It certainly isn't "everyone". A fair-number of people in my large bike club use phones.
And, some of the computers aren't that expensive (especially, compared to some of the GPS watches).
Why do I need to have a map continuously in front of me?
What you need or don't need doesn't have much to do with what works for other people.
I use a Garmin GPS watch to track my path and ride statistics for later review. On the bike.
Since your phone can do this, you really don't need the watch.
