I was going to say .NET but then you mentioned FS. You are right, FS is definitely the coolest MS product in my opinion! For me at least that is the program that got me into programming in the first place. I have played it since the DOS days and it was my first computer game (ok so its more of a simulator than a game) Ever since then I fell in love with aviation. In fact, it drove me to solo an airplane on my 16th birthday and get a pilots license.Sven Groot said:
