Did anyone buy the smart cover? My Pro is being delivered tomorrow and I'm contemplating ordering a smart cover that would hopefully arrive then too. What is the part like that attached to the Pro? Is it completely covered material that sticks to the Pro or is there some exposed metal that could wear away the Pro finish over time? The last time I tried a smart cover was iPad 2 and at that time, there were some areas that were metal that snapped onto the iPad and many reported some marks on the iPads over time. I didn't know if that changed and the magnetic and hinge part might be completely covered in material now? Thank you! Enjoy your pros!!
