One of the nice things about the 30 pin connector was its intrinisic strength. Unlike mini/microUSB, it not just provided a connection, but strength to hold the iDevice upright and even provide resistance against bending/shearing. What I'm wondering is how good/bad the Lightning connector will be in this department for holding a device up in a dock. It is smaller, so it has to be stronger because of less area. I also wonder how many insertion/removal cycles it will be able to take. The 30 pin has performed admirably in this respect, easily handling thousands of connections and disconnections, while some other connectors (some USB variants) end up snapping after a while. For the iPod and iPhone, it isn't as big an issue as the iPad, which needs as much strength as possible.
