My one tab broke off of my OEM holder last Thursday morning as I was walking out of the house to take the family to Disney World for 4 days. Not good timing, I had to buy a case @ the airport that worked but was 45 bucks and not a great fit. At least it has a magnet in a good enough spot to put it to sleep.
I am sticking with this case till new/better options become available- either from RIM or elsewhere- I have yet to see one I like.
Not happy that the tabs broke that quickly!
