Windows 7 Better than Vista?

From what the developers at Microsoft are saying, this one is supposed to be better and aren’t they all supposed to be as Version 7 is the next gen? Well, it’s not supposed to be a ram hog like Vista, therefore faster processing times. From articles over the internet, the different is minor at best and is definitely nothing to jump out of your seat about and will probably not be worth the time and effort to buy, install and or upgrade Vista, whereas Vista is reported to be between 35-45% SLOWER than XP, a lesser version of itself. What’s going on Microsoft? This just means new drivers, new components and a whole lot of wasted time for literally nothing.
