Changeover

Guys, a confession to make. I'm on an illegal ms xp pro (sp2) os. Have got only one legal version, i.e. my xp home edition, which is installed in another pc of ours. However, I've decided to switch over to a legal version (sooo honest, am I not?  :P ) . Anyway, was thinking over my options. One is obviously xp pro, which is costlier than both xp home and media center, but has better networking features than both. 

   Yet, I've heard that the media center edition has xp pro as its core, and the media center software over it, which will save installation of a picture manager (yes, cost is a factor in India, even though I'm an Advocate!). 

 Hey, why don't you people leave a comment suggesting which one to buy? 

  P.S. I use my pc both as an office (documentation, email, internet surfing, etc.) as well as for domestic things like dealing with digital pics, listening to music, etc.
