Yes, of course, but to me it looks like it'll cop out at the times when I need the most efficiency. Forgive me if I'm wrong but this is my thought process.
Say I'm editing high quality video files, this requires a lot of RAM, constant access to the HDD and is CPU intensive. So then Vista will start wasting my CPU cycles loading an unloading programs from the hard drive, anticipating how much RAM it thinks I need. AND the access of the HDD to load the programs, is reducing the hard drive access available for the program I'm using. When I'm doing something intensive stuff like this I don't need extra complications that may cause my program freeze. After all, if the next OS is more efficient, why should it need a better PC to run. With every generation the software gets more and more bloated. The premise behind reducing the amount of RAM you have is silly, but reducing the RAM you need is not.
I may be wrong, if I am please point it out, but that's the reasoning behind my opinion.
