I ordered the N700 lapdesk for Christmas my boyfriend because he plays a lot on his PC and he studied computer science. The surprise on his face was great to see. He could not wait to try it in front of everyone. Our surprise was great also for the quality of the sound that came out of a sudden one. When he plays, he is completely caught up in his thing and it's just whether he intends when spoken so the sound is good. I am myself served for watching a TV series and haha what a difference when I make of him and defer to the mere sound of my pc ...! For what is the fan, it works especially well during the games. The pc finally rest at normal temperatures and above can be used on knees, as in the chair in the bed or other comfortable thanks to the small cushion. I do not know what it is about the autonomy of pc since the games need to be on AC power. The only negative is that it's a bit cumbersome. On weekends we go to our parents and I see us not lugging lapdesk in the train. However, I remain very happy with my purchase for a reasonable price (thank you Amazon!) Compared to other outlets.
