Would you sell your info to Microsoft in exchange for a USB flash drive (I cannot see how big it is).
This is a tough one. It isn’t a KFC Buffalo Snacker Sandwich, but it isn’t too much more expensive.
It is Microsoft, so chances are that they have already licensed your soul so what difference does your address make? The drive is filled with Microsoft licensing information so at least you can see if they really do own your soul.
Free USB Drive? Oh, why not? I’m sure MS has that information on me from registering my free Visual Studio Express Editions.
