I'm going out to a couple of sports stores this week and I'll check out the ones they have. I've looked at a few that people have suggested. Of all of them I like the interface on the Garmin Forerunner watches - big buttons on the face, the bend and the wrist placement on the face of the Nike's and the big display on some of the Timex watches. I like the features offered on the Polar watches. Am I screwed or what?
So what's my solution when I have too many choices? I make my own. I found this:
Sport Armband Plus with FastFit for iPod touch (2nd Gen). What I can do is build the app that I want right on the iPod and just bolt it to my forearm.
I think it could work.
Anyway this is the backup plan for being disappointed at the store. [And I was just in China and could have bought the best knock off watch for peanuts. Of course it would have told the wrong time and had only 55 seconds in a minute - but it would have been cheap!]
