They're working with DexCom -- here's a link to some info: http://www.medicalnewstoday.com/articles/93235.php
The guy we saw was from the OmniPod bike team, and he was wearing an OmniPod and the Freestyle Navigator CGM, which takes up more skin space than the pod's do. My daughter took a look at the two together, and said, no thanks! He also told me they're working on improvements to the PDM, like a color screen. I hate to tell you but the not wanting to check the blood sugar when you're out, or around friends, etc., only gets worse. My daughter even argued with me once about checking her sugar when we were at her endocrinologist's office!
Occassionally, the pods seem to just not insert well. We know it's a pod issue because she'll have a couple of ridiculously high sugars, and then I have her do a shot. If it goes down after the shot, it's the pod, not what she ate, etc. Not always easy to know with a teenager! When they replaced the box for me, they did ask for all of the remaining pods back, which wasn't a problem because we weren't going to use them. And, they sent a prepaid box for them too.
Overall, like you, we love it. I can't imagine her having to deal with the tubing of other pumps. And, she definitely prefers the omnipod to shots!
