Are you a newowner getting frustrated with Apple for not yet releasing a Mini DisplayPort to HDMI adapter? Sure we all are. Well, maybe some of us.
I mean, you could shell out $900 for the Apple "I only use Mini DisplayPort" (not an actual quote from the monitor) LED Cinema Display, but seriously, unless you're an AIG exec, who has that kinda scratch these days?
Anyway, Apple has yet to release an official adapter that would allow you to connect your pretty little MacBook to an HDMI-based external display. Thank goodness then for the free market.
Yay!....what? Oh, the display you wanted to connect to your MacBook doesn't have an HDMI connection? No problem, 'cause BAM! Monoprice has a Mini DisplayPort to DVI and Mini DisplayPort to VGA for $15.20 and $18.85 respectively.
Apple offers its own versions of those last two adapters, but is currently charging $29 for them.
