Re:Hello! You get both operating systems. (Score 2, Informative)

Look folks, the reason for the extra $50 is simple. You get both Vista AND XP.

I think you're wrong.

I'm trying to buy a Dell laptop today. Here are my operating system options:
Genuine Windows® XP Professional, SP2 with Media add $0
Genuine Windows Vista® Business Bonus-Windows® XP Professional loaded [Included in Price]
Genuine Windows Vista® Ultimate Bonus-Windows® XP Professional loaded [add $50]
Genuine Windows Vista® Business Service Pack 1, With media add $0 (Dell Recommended)
Genuine Windows Vista® Ultimate Service Pack 1, With media [add $50]

You'll notice that (1) XP loaded, (2) Vista Business loaded, and (3) XP loaded plus Vista Business on media are all the same price. It sounds like beginning tomorrow either of the XP options will carry an additional charge.
