I'm planning on buying a tablet, and I'm trying to decide between a Galaxy Tab and the Blackberry Playbook. I'm planning on using the tablet for mainly web browsing (watching YouTube, listening to music online, playing Flash games, etc.) However, I also need to know if the Galaxy has a filesystem with folders for documents, music, pictures, like Windows Explorer and Mac Finder. Also, is it possible to download files from the Internet, such as mp3s, videos, or text documents, onto the Galaxy, or are you restricted to only downloading apps like you are on the iPad? Additionally, is the web browser's Flash capability sufficient for watching videos and listening to music, or is it spotty and slow?
