Windoz XP buggy operating system

I want to share my valuable ridiculous experience with win XP. At first I wondered about the XP look and feel. After working on that I came to know its only a mask not really sophisticated. Because considering performance its too buggy. Compared to my Redhat 9 system its easy to operate but too inconvenience for performance. I think windows 98 SE only the best operating system among Microsoft's entire product. All other products are buggy. But we have to follow their marketing technology. Because at first they release beta version only with the option of bug reporting. People have to buy that product on cost and enter their problems as a report. Based on that report they improve their product and sold it for higher price. Nice approach :). Because if they want to increase the quality of their product, they should have one R&D team. Instead of using this bug reporting technique there is no need for spending much more money for R&D. They are optimize their cost using this bug report technique.
