I think the biggest question is when would we even see a second gen in a year or maybe 2 ? I can't see them doing a yearly update. That's what makes me want one now versus waiting another 2 years. Still can't decide if i should dip my toes with the sport, but the stainless that Scott Stein from cnet was wearing looked awesome.
The part I found interesting was when she said she watches her heart rate come down after a workout. In week 4 it noted "By flashing its LED lights hundreds of times per second, Apple Watch can calculate the number of times your heart beats each minute during your workout. That measurement is your heart rate." Obviously not as accurate as a chest strap but seems like it's going to be a very accurate bpm.
