"Let me get this straight you are I think asking will Vista run on a 486 with 16 megs of memory ? Well I would say no the rest looks kinda confused ." No, actually I was just being facetious with my post. What I was suggesting was that if the Vista software incompatability problem with legacy applications was that users didn't have enough "horsepower" to run them on their Vista machine, then these applications CERTAINLY would not have run on Windows 3.11 and subsequent OSs. I am speaking strictly of software incompatability here. I am totally satisfied that the reason that older programs didn't run in Vista was due to Microsoft's policy of planned obsolence and not due to any computer hardware shortcomings. And I am not being facetious about that.
