I completely agree with you and maybe I am just frustrated to have this great port for no apparent personal use (got an display and don't need a raid drive). If Apple would have at least offered an adaptor at the same time THAN I can understand it. But putting it in there, offering ONE periphery device themselves only months later and otherwise hyper-expensive hardware doesn't cut it. At least provide adaptors FROM THE START so that the port is usable. Currently I lost a port.
How did you lose a port? Virtually every PC on the market has a video out port on it somewhere, yours just happens to have a little lightning bolt near it. Maybe in the future, you'll even find a use for some of its other capabilities.
You do realize that there are scads of $6 adapters already on the market that allow you to connect virtually any display out there to your TB port?
