Durability - the legends will go, but the keys will still work longer, than other Razer boards, as long as people are bathing them in liquids. The lights, probably just as long as other Razer backlit boards. One wouldn't expect them to change their LED supplier.
The real question is whether folks will understand getting their board serviced (new key set, legend stickers, switch replacement, etc.), rather than buy a new one, when something happens, to get the most out of their investment in a mechanical board.
