I have a Samsung Chromebook+ that can run Android apps. Prior to LR 3.0 it was able to see and open DNGs from my phone and ORFs from my camera. Helpful for quick edits. But with 3.0 LR will only see JPEGs even if the DNGs and RAWs are in the same folder as the JPEGs. My other Android devices can see the DNGs and ORFs just fine. I hope this gets fixed, though I'm sure the response will be something along the lines that LR isn't tested to run on Chromebooks.
