So i recently took part in a microsoft survey about flight simulation games and many people did this and when the entries ended they randomly selected about 40 people to recieve prizes from microsoft!!!!!!!!!! hell yea!!!!! this is totally for real. Now i need help they have given me the option of selecting one*(1) of the following: ...Thank you for your participation in the online Microsoft Flight Simulator Survey. You have been randomly selected to receive a gratuity. You may choose one item from the following: Visio Pro 2007, Office Pro 2007, Vista Home Premium, or Vista Business Edition...... I was thinking vista would be the only logical choice here, i have no business but idk and idk what visio is or used for and then theres office which i dont need but guys what should i pick!
