1. How much of Object Desktop has been designed around the Vista WDM? I understand that TweakVista (which i am currently trialing) and VistaLogon are specific but wondered about the rest.
Many of the components are taking advantage of the DWM.
2. Can you use ObjectBar to simulate what ObjectDock Plus does (e.g. multiple Toolbars, etc)?
While you can create "docks" and application launchers with ObjectBar, I really can't compare it to ObjectDock.
3. What is the discount available from getting ObjectDesktop (and will it work the other way if I buy ObjectDock Plus first)?
You get 25% off ObjectDock Plus if you are an Object Desktop subscriber. The only discounts available for Object Desktop is if you are upgrading from WindowBlinds, DesktopX, IconPackager, etc.
4. Any chance I can get my Survey email confirmation with the Discount code resent as I seem to have managed to delete it ?
I'm not sure the survey is still active. You would have to contact sales regarding that.
