Related but similar question . . . if you don’t care about a fancy touchscreen, is there any real advantage of the 610 over the 410? I guess the wet bezel problem wouldn’t be an issue, but I’ve never thought that was too difficult to manage. The 610 seems unnecessarily complex to me, and when I played with one I did not like the way the touchscreen worked. I thought it would be too difficult to operate while running (I was having enough trouble doing it standing still and focusing on it). It also has a couple less hours battery life than the 410 and costs a lot more.
if it makes your decision easier- the 410cx is on sale at WalMart right now for $159. And that’s with the HR monitor. a steal!
