As you probably know, since 2009 the iMac has been able to act as an external display. However it requires a ridiculously expensive adapter. 3 years later, I still can't find a cheaper alternative to either of the above, and no matter how much I'd like the feature, I'm not paying $150 for a cable.
So has anybody made a more realistically priced alternative yet? It can't be that hard surely!
