Yes it’s true I could probably do it that way, but what I want in a fitness watch is a phone replacement while working out. For example, I don’t carry my phone on a run. For weight lifting, with my old Samsung, I just left my phone in my locker and used my app to record the weight lifting I was doing. I could switch back to a workout I hadn’t done in a year and see what I was lifting then. I never even thought about my phone, accidentally leaving it at the bench, or worrying about damaging it. It’s really freeing to just get away from the phone for a while.
My point was just agreeing with the previous comment that, while Garmin makes a great watch, their software could be improved. The limitations they put in are also somewhat arbitrary. I have plenty of storage for songs and podcasts, so a couple MB of data storage should totally be fine.
