The computer speakers I have at home are the Logitech Z-5500 5.1 set iirc.
Pretty big set, and didn't feel like dragging those with me to this school and having them take the space they do. Considering everything had to fit in a sedan and I'm living in a hotel room, space was a concern.
Thought I'd be fine with headphones the entire time for computer use. When playing games I prefer the virtual surround headset I have, as there is more immersion than having a 5.1 set with all the speakers in front of you.
Picked up the Klipsch ProMedia 2.1 set recently on sale at Best Buy, have to say, I'm loving these. And I can barely use what the set offers, as again, I'm in a hotel room. These things can push out massive volume on mp3 files, and I have the sub setting extremely low. Not sure if they can be heard outside these walls, but don't feel like agitating neighbors.
Great 2.1 set, and it may actually be better for most purposes, especially since a 5.1 set isn't all that impressive when you have them set up with minimal surround style, all spread out in front of you.
Once I get back home, and hopefully get a chance to finally move into my own place then, not sure what I'm going to do to. Going to have to decide between the two sets or find uses for both. hmm
