The official launch date of the new operating system Windows Vista has not yet been set.
When will the final product be launched? Enter your guess now and win an exclusive invitation to the international Vista launch event in the USA
In addition to a first-prize trip for one person to spend three nights in a four-star hotel and attend the launch -- the location of which has not been disclosed -- Microsoft is offering second-, third- and fourth-prize winners a new Xbox 360, and fifth- through 10th-place winners an Xbox Core System.
This contest is only available for the EMEA users and can be found here.
So I suggest all to join the beta experience and try Vista and maybe win the trip.
