Query: not compatible

I could not keep this product because VISTA IS NOT COMPATIBLE!!!! I then purchased, from you, a Tungsten E2 and finding out that VISTA IS NOT COMPATIBLE for this either. This is the most frustrating problem I have dealt with since I started using the computer in the early 1990's! MICROSOFT has developed a lame program and all manufacturers that deal with the computer that is not a MAC has to bow down to them which is wrong and not good business practice.
