I'm always impressed with the amazing work you guys/gals do but it's terribly disappointing that you don't seem to want to design for Windows Vista. I don't have anywhere near the knowledge required to design these themes so I admittedly don't know what it takes to design for Vista vs. XP.
However, there are millions of Vista users at this point and that number will only continue to grow in the future (Windows 7) - also taking into consideration that XP will no longer be supported.
I'm not sure what you're hearing from other people but I can tell you that I, for one, am out here waiting to pay you money for your work...as soon as you stop ignoring me (and millions of other potential customers) just because I/we use Vista.
With that out of the way, , The Skins Factory/Hyperdesk team includes some very talented designers! Everything I've seen is top notch quality. I just hope you finally accept that Windows Vista/Windows 7 is, and will be, here to stay - like it or not (sometimes I do, sometimes I don't).
