I think you probably mean Thunderbolt, or maybe Firewire, and not Lightning, yes? Lightning is the connector found on iPhones. I don't remember people complain

I think you probably mean Thunderbolt, or maybe Firewire, and not Lightning, yes? Lightning is the connector found on iPhones. I don't remember people complaining this much about adapters when the Firewire 800 port was a different form factor than the Firewire 400 port that came before it - most of the equipment that plugged into it was "pro" level hardware like you mention.
