I have a 14 and 11 year old. I am sticking my fingers in my ears and  
going "la,la,la,la..."

I think that enterprise licenses are substantially lower than this for  
the whole MS shebang.  Maybe not.  Having the body sit at the desk  
already costs you $100-200K/yr, so an extra $1K/yr is down in the  
noise level (especially if it's perceived to be more trouble to get  
rid of it than just to pay it again...Clever folks these software  
marketing companies...)
