I have listened to music and watched movies etc on this laptop with the privilege of a quiet environment and not quiet environments. With every experience I was and still am satisfied with the sound quality even when listening at maximum volumes. This is a great laptop allround!
I don't know what the resolution is, but the play back and the camera are both good quality. I use the camera for Skype and there is seldom pixilation. When I play movies off the net there is no buffering, the only buffering problem occurs when there is a video off yahoo, or msn news.
Playing games on this machine sucks big time...the touch pad is so sensitive on this Windows 8 that the cursor opens the charms at the right whenever it feels like it and changes the text and image size at random times. The computer is the most frustrating machine I've ever used. It's pluses are its speed and its quiet operation. The display is also pretty awesome in its brightness and clarity.
