Look, there's no arguing that Apple charges a boatload for its first-party adapters, and this isn't the first time that one of those overpriced dongles has caused an uproar (Mini DisplayPort to Dual-Link DVI Adapter, anyone?). But when the company trots out an iPad Dock Connector to VGA Adapter and promises to enable users to "see their videos and slideshows on the big screen," it should probably make a few clarifications. Instead, more than a handful of consumers are revolting over on Apple's own webstore, noting that any video laced in any type of DRM (iTunes flicks and Netflix streams included) won't output at all. Contrary to popular belief, this adapter doesn't actually mirror the iPad's display, which is fairly absurd in our eyes -- teachers are even stating that Apple's own Pages and Keynote apps won't output via the dongle, making this effectively worthless for blowing up presentations for all to see. We (sort of) get the DRM thing, but not including support in your own presentation app? Unacceptable. A tipster has noted that Apple informed him that "it's up to the app makers to enable the video out function," so we suppose all that's needed to solve a lot of controversy is for some switch to be flipped in some direction. Any other hang-ups with this thing that the world should know about? Drop 'em in comments below.[Thanks, Tony]: A few tipsters have noted that Keynote does in fact work here. Here's a growing list of what does and doesn't work with the adapter.
