Question about Amazon Kindle Voyage

The device is purely an e-reader (on which you can read e-books). otherwise you can't do anything with it.

I don't know about the Voyage, but the Paperwhite has a "beta browser", beta because it's still in development. It will probably be on the Voyage as well. I have read that it can often crash, but I have never used it. However, you can use it to access the internet, but youtube or anything else won't work because the e-ink display is not designed for that. You can't take photos with it because it doesn't have a camera. The display can only show black and white or grey tones, so it's not ideal for looking at photos...
