I will try to do as much as possible for you
I can do that with my Acer W700
I don't think I can endure that the screen is really bright!
I don't have Netflix, but I can stream something through torrent with a bandwidth cap slightly above the movie's bitrate. That should yield very similar results
Hmm, I don't have a NAS but I have a desktop with SSD and a gigabit ethernet connection to the router, so I can host an FTP server on it and transfer files that way
