Despite it just being a concept at the moment I have to say that the Holga Digital looks pretty well thought out and appealing. There is no LCD display involved so the "delayed gratification" is in place to simulate film use - you're never sure what you captured until you actually import the images. It is fairly bare bones in terms of features and settings but done so intentionally:

The original Holga camera has so few functions that you don't get distracted by the technicalities. The Holga D camera is also based on the same principal. Even though it has more functions and controls compared to the analog Holga but it is designed in such a way that it discourages fiddling around with camera-settings and and encourages you to just shoot without thinking much.

Check out the entire writeup and just try and tell me you wouldn't want one of these around (assuming the price point wasn't insane).
