I'm getting to this discussion late, but YES, I am switching from the pods to Minimed!
I haven't been totally dissatisfied with Omnipod-- I've certainly had my share of surprise occlusions, pods failing during priming, etc. Even had my pod screech to a halt during my wedding ceremony! I've had a hard time getting a hold of customer service since the smaller pod switch, even having to place the same order three times. Used to be very impressed with their service previously, since 2008.
My changeover is based primarily on wanting a CGM that is integrated with the pump. If the Omnipod Dexcom pairing had panned out, I would have gone with that. My insurance is willing to pay for a new pump so I am going for the 530g/Enlite.
Another big factor for me is the cost of using the Omnipod-- In 5 years of podding, my insurance was not always spectacular, and I would pay $30-$45 per pod (out of pocket). When a pod occluded or the stickiness wore off before the full three days, I was S-O-L. I just don't have the money to spare.
So you can go from pod to pump! I don't begrudge Omnipod at all, just have to do what works for you.
