A:AnswerI believe 1 year, but buy additional Geek Squad warranty if you can, invaluable, my son dropped and broke his screen and the warranty covered it.
A:AnswerNo. But you can use a mini SD card for extra storage.
An idea that I haven't tried is using a mini hdmi to female usb cable. That might allow you to use a usb drive but i don't know for sure.
