Huh... it looks interesting. However, I don't think I'd want one of the first few. So many new ideas, I'm just wondering which will be the biggest issue.

Also, I like being able to wear all different stuff... and running stuff does wear one (esp shoes!). With how expensive HRM stuff can be, I don't know if I want to know what all that would do to the cost of shoes ever few months!!

Cool idea though... I'm interested to see what other companies pick up similar, and how it works in practice.
