Which size Vortex i7 are you looking at? I'll grab the necessary product sheet and have a look for you. I'm afraid we cannot offer any Military discount or free fast track services
This is fast becoming a popular question and therefore we are going to list the details under the "display & graphics" section in the "detailed specification" tab on our configurators.
As soon as I have the information I will update this thread for you too
Regarding the sound, the laptop uses Intel High Definition audio, and has four speakers and a sub-woofer, and so the quality should be very high and as good as, if not better than your existing laptop.
