Facts getting in the way of headlines?
The Win 10 phone tech preview, which just as a reminder is full of alpha and beta components, isn't bricking peoples phones - that was the recovery tool which looks to have been resolved.
As for the 100 days meaning the UI won't have time to change much - I've seen lots of changes in the UI over the course of the preview, and many significant ones just from one build to the next. I've no reason to think that any UI changes couldn't be introduced before the consumer preview, or the RTM version.
