Even though Microsoft has claimed that they have sold many copies of Windows Vista to the market (20 millions by March), it doesn't mean that everybody is happy. For many people, Windows Vista may bring something that they have never imagined before. A nice looking desktop with Aero technology, bringing a new look and feel and also experience that they have never had before. But, in order to get the best of it, they must be prepared with the monsterous hardware requirements. Some site claimed that it will be on it's best performance if you have 2 GB of RAM and high level of VGA Cards.
Acer president Gianfranco Lanci said that the PC Industry was very disappointed by Vista since the new operating system was riddled with problems and gave users and businesses no reason to buy a new PC. Many applications doesn't work at that time (and probably some are still up to now), and many drivers aren't compatible with Vista (it's getting better though), and many more. Will this happened again on the next release of Windows (dubbed as Windows Seven)? I hope they don't make another mistake
