Today I got my free Windows 7 Ultimate Steve Ballmer signature edition, 9 days after the launch date!
I collected the same from the nearest BlueDart Collection center an hour ago. I remitted 1064 rupees as customs duty at BlueDart.

The Windows 7 Party Kit Contains the following :

1. One limited Signature Edition Windows 7 Ultimate ( 32 Bit & 62 Bit versions on separate DVDs )
2. One Puzzle with Windows 7 Desktop Design
3. One Poster with Windows 7 Desktop Design
4. Ten Tote Bags with Windows 7 Desktop Design for hosts and guests
5. One package of Windows 7 napkins
6. One table top centerpiece for decoration

I read at some blogs that the USA party packs also included the following:

• One Deck of Playing Cards with Windows 7 Desktop Design
• One package of streamers for decoration
• One package of balloons for decoration
