Haha yeah way to focus on the silver lining! I only wish I was able to do the same.
I'm not sure the vibrate rattle will be "fixed" any time soon, it might be related to a hardware design issue or supplier issue, in which case we won't see something solid for a while, and you'll have to rely on getting "lucky" devices that magically don't have the rattle. I've gotten used to it at this point; the only thing I'm worried about is whether or not the rattle can cause further loosening or degradation of the parts involved in the rattle, or any parts that may be getting abused physically when the phone vibrates.
If I can be sure the rattle is purely a noise, and not hardware loosening or degrading, then I can live with it. However, I don't know what it would take for me to have confidence that it's true. I'm not sure a statement from M$ or Nokia would do it, as I've had the wool pulled over my eyes by manufacturers before (*cough* Crapple *cough* Samsuck *cough*).
Yeah...we'll spend the rest of our phone buying days pulling wool I think. Its a choice I made to play...so can't complain too much.
I found I only hear the clang clang vibrate on restart of device. Regular vibrate is ok. Don't know why that would be. I also got rid of the Purple-ish screen with a hard reset. I only saw it when brightness was on automatic. Switching auto off made it go away....to me, that doesn't a problem fix. So, I hard reset once again...and it no longer showed up on Auto.
Another thing I ran into...I've had 4 WP devices in the last 3 months...a 710, Focus S, and 2 900's. I ran out of device space in marketplace...couldn't reinstall apps. I had already took a device off to get the first 900 on board. Wasnt elegible until May 7th. Called MS and they said 24-48 hrs. Bummer.
Got to work this morning and Marketplace was live again...Cool...I only had to live the night with no apps.
