You can download, watch, listen and read from the SSD while offline. You can also do the same from USB. Chrome has a file manager that allows you full access to your SSD and Chrome has the apps to do the things that you asked.so I can't download mp3s, mp4s and listen or watch offline? How about ebooks?
Here's a link to a review stating so. I've seen the actual screenshots of it too, I think it was techcrunch.com but couldn't find them again.Great, so it can be used when offline!?
I found this on the Google site... Supported file types and supported external devices...As others said, you can play media off external storage, e.g., microSD card, USB stick, camera or your phone in 'storage' mode. MP3, MP4 and JPEG work; WMA/WMV do not. I don't know if there's a list of currently supported formats somewhere.
