Why not the Envy 17 with the headphones, your already paying enough for it. The Envy 17 looks nice though, and it doesn't look like that bad of a gaming laptop (the parts are very similar to the Acer Aspire 8943g, which does fairly good at
benchmarks) and the sound features are only a bonus.
If i really needed a headset, the Envy 14 seems like a good choice, and an alternative to a 13 inch apple laptop.
Why is 3d still so "in", I don't think it works that well yet, but that's only me. If 3d was really so revolutionary then apple would jump in.
