Connector wear and obstruction is real and can make charging or wired interaction extremely hard or even impossible. Connectors also have a lifetime.
For example, my phone's (Samsung Galaxy S6) port has dirt in it that I can't get out, some micro USB connectors wont fit and all of them don't stick in and readily fall out. This is one of the reasons I absolutely loathe and hate micro USB. It's just an extremely bad connector.
Compare this with my Surface Pro 3 (or the magnetic Mac chargers): the magnetic charger is wonderful and Just Works.
Wireless charging is the next step. Sure, you need the pad and it's not as readily movable but damn it's effortless.
Personally I'd prefer magnetic connectors, though.
