On the insurance from the Microsoft Store, here's my experience:
1. a week and a half after my first 928, I had a problem (don't remember what), took the phone in and they handed me a new one.
2. While walking out to the car with that phone, I realized that the new one was stuck in a loop - couldn't even sign into my MS Account. Walked back in and they handed me a new phone.
3. A few weeks later, had another problem (don't remember what), walked in, they handed me a new phone.
4. Broke the screen. Walked in, handed them $50, and they handed me a new phone.
5. Got tired of the "phantom tap" problem - screen acting like there was a ghost reaching over my shoulder and tapping the screen while I was looking at it. Went to the store expecting the same experience as prior episodes. Was told that they could ship it to Nokia and I'd be out my phone for a couple weeks, or I could pay the $50. I argued the point. If I know how to do one thing, it's argue. Got the manager involved. She saw my Widnows Phone shirt and asked if I was one of their developers. Yes. :wink: She told me that the way it works is they can send the phone to Nokia and get it covered by warranty, or pay $50 and get coverage under the MS insurance. I told her that I used to administer extended warranty contracts for a major insurance company, and I'd bet that if they looked at the terms and conditions they'd find that the insurance doesn't cover anything that is covered by the OEM warranty, and this problem would be an OEM issue. She told me that she'd have to research that, but I could be right. I explained to her my past experience, and she said, "Well, I didn't come over here to tell you that you were going to have to pay the $50. We'll go ahead and replace the phone."
While ringing it up, the person helping me got rather snarky... And when I went to grab the box after taking the phone out and putting my SIM into it, he wouldn't give me the box - he said, "It's our box." Ooooookaaaaaaayyyyy... Funny, since initially he put the whole box into a bag, with the phone still in the box, until I took it out to put my SIM in. But whatever... I got the phone replaced.
