I've yet to see anything that makes the removal of a 3.5mm jack seem comparable. You couldn't use DVI or HDMI without replacing the port, which isn't the case with Bluetooth (which you can use regardless of having a 3.5mm jack or not).

A more apt comparison in my eyes seems like wireless mice/keyboards. They don't have cords so they're significantly nicer for cable management, look better on your desk, have longer reach, and probably have other benefits (as well as their own set of tradeoffs like latency, battery, etc). You can use them now or you can use wired versions... but just imagine if a company started selling computers where you could _only_ use wireless keyboard/mice unless you bought USB dongles. Sure, you could just buy the dongles and deal with the loss of choice/convenience, but... why would you want to?
