First, thanks for your thoughts on Applecare. I think I will skip it this time. It has paid off for me with the Macbook Pros I've owned and with my ipad.

Where is your phone when you are cycling and it thinks you are walking? It never happens to me, and I'm glad about that. It seems to know when I'm walking and when I'm not. It does not infer that I'm cycling, ever. I normally keep it in a mount on my handlebars, but sometimes it's in a pocket.
