Quote: "XP only has another year of support left in it anyway"
XP won't suddenly disappear because support will stop from Microsoft. The OS will still be used for up to 3 even 4 years after that (even by gamers) and certainly by developers (bigger user base).
Another point to consider is the new operating system from Microsoft that is already overdue. It was scheduled for release this year. Vista as good or as bad as people think it is (I'm getting used to it now on the other comp) is heading for the same lifespan that Windows ME had (ugh!) The new OS has been delayed by approx 2 years due to problems. I wouldn't be surprised if the majority of people considering moving to vista have never heard about the new OS, Microsoft are keeping it fairly quiet, but a lot of hardcore PC enthusiasts are waiting for the new OS and won't even consider Vista, seeing it only as a stop gap measure (Win ME).
The original poster wants X10 features on X9. That is exactly what Lee is doing now, working toward the migration V2.00 I hope that it is completed soon so X10 can be upgraded to something like it originally promised to be.
