Not necessarily a fan of touch screens myself. What features are touch screen while running, switching from one screen to another? Also, does anybody know if a HR monitor from another model Garmin will pair with the 220? I know you need the specific one for the 620 if you want to be able to use some of the features of that watch, but I'm wondering if you can pair another Garmin HR monitor with the 220. For example, I was able to pair the HR monitor I got with my 405 with the 310XT with no problems and my friend's 210 picked up my HR monitor one day, so I know it pairs with multiple other Garmin models.
