I have a mint condition Microsoft XP Go Pro! collectors kit. It comes with a full retail version of XP Pro, and license key. I can also include a burned copy with SP3 slipstreamed in if you like, which will work with the same key.
It has been in the box since the day I recieved it (new), the bobblehead doll, baseball, cards, etc, have never been opened. I hate to see it just sitting in the closet when I know some people still use XP.
$49 or b/o, shipped anywhere in the lower 48 states, will be double boxed to insure it reaches you in great condidtion.
Although I haven't used it for years, I do have heatware under the same username as here.
