The funny thing is that most long time computer users complained loudly about the GUI-centric shift that happened with Windows 95 back in the day. of course, they all got used to it after a while and came to like it just fine. the lesson being, so long as the new interface isn't buggy or horribly flawed, it will probably be accepted by nearly everyone after a relatively short time.
First Apps contest: If you're a finalist First, congratulations! You'll receive an email by January 15 detailing the next stage of the contest. You'll need to update your app to run on a new, confidential Windows 8 build provided by us. Then, you'll resubmit your app before February 3 for the final round of judging. Microsoft spread many over the next days and then there are always a leak. sM4llziE so you must be fast.
Every build will be a rebuild of and older build wit code change and updates they do not rewrite from scratch for every release you would be waiting for ever if that was the case
I think that MS want to populate the Store. And them can't do it with app developed for very old build. I think the winners will have a build that contain at least the basic changes for the beta.
