I've found watching my netflix anime on my 3DS to be better than dragging my laptop into bed for my nightly episode or two. My wife complains, constantly, if I watch it on the TV in our room as every anime is oh my gosh super quiet during conversation and, out of nowhere, UNGODLY LOUD FOR NO APPARENT REASON. Hard to sleep through, neh?
But with my 3DS I can have my finger on the slider and immediately adjust the volume without it disturbing her. All while not having a burning hot laptop on my chest with headphones on.
