My complaint, and a legitimate one based on the reaction to these repetitive posts, is someone who isnt a developer COMPLAINING ABOUT A DEVELOPER PREVIEW AND ITS BUGS. The only thing interesting is that they arent filtered. If you want the finished product, wait. But I forget, this is the internet and everyone is special and has the right to complain. IMO, I'm a dev and I dont want the general public using my preview. OR, heaven forbid, MS be selective about who can get it if they arent a dev. How about if you want the dev preview, you have to present bi-weekly reports to MS. If you dont, your phone is frozen. The finished product isnt helped AT ALL by someone who goes back to 8.1 and doesnt have a legitimate reason to.
