DSLR Camera or Camcorder

[rax_7]

i saw a Nikon D5100 , it can shoot 1080P video. i also see some digital camcorders. they can also shoot full 1080P video. and i am sure most camcorders have a button or a feature that can take a snapshot. they both seem like that can take pics and videos. so should i get a camera or a camcorder?
