Microsoft decided to skip 9 and charge straight for 10. The company has managed to build some anticipation without telling us what to expect. If the up-and-down pattern holds, 10 ought to do better than 8. Whether 10 is better than 7 is another matter. 7 had all the basics, and it did all the basics well. No more blue screen of death. You could search your hard drive without waiting forever. The engineers in Redmond seemed to solve Windows’ more serious security problems. I expect 10 will preserve these good qualities, and make people feel like they have the latest thing around. People do like to have the latest. To be cool, you can’t wait too long to buy.
