So, I had an idea for an iPhone app today. And like a poor Mac user I immediately set to work, only to be disappointed yet again by Apple's closed-ness.
How cool would it be to scan barcodes using the iPhone's built-in camera, and be able to Google up the product? Read reviews?
Unfortunately, in Apple's infinite wisdom *cough*, there is no access to the camera from the SDK. Oh well, so much for revolutionary device eh? :)
