I guess we finally got an answer to why they removed the hard shell cover that we complained about not having.

I've noticed it going either way, although my observations aren't based on actual testing, just normal use and unconsciously taking notice. Some go up, some go down. (They do this with each rescan even if it's still in case on or case off configuration.) Then again I'm in downtown Toronto so the sheer amount of radiowaves should be turning me into a giant tumour at any given time.
