just looking at a lap top

[Canada]

I won't take it out side my home but I like the idea of being able to from room to room.

I'm looking at $ 1000 as my budget.

Terabyte memory
audio outputs that can hook up to any speaker.

Can some one explain how audio outputs to say B&W or Paradigm speakers actually work. Because I have no clue as to the inner workings of a computer. I was born into a generation of people who should not have to ask these type of questions damn it!

Can people private message me with the answer, as well as posting it so every one can see it.

Thank you!
