continued changes in Vista's launch time frame

However, continued changes in Vista's launch time frame, even if it indicates a more stable and secure Operating System will be launched (or that is the theory). Microsoft's OS and webbrowser pattern is poor as it is:
Internet Traveler 7 is set for launch in the first half of 2007 and Ms windows Windows vista is set for common launch in the first quarter of 2007. Both items will provide many improvements and additional features over the older versions but the truth is very little of it is new.
One function to finally reach Online Traveler is tabbed internet browser. To a non-technical individual, who just uses what's supplied on their MS Ms windows desktop computer, this may seem new and interesting, however tabbed internet browser has been around since 1996 (although it was a function in a non-public beta edition of InternetWorks since 1994) and has been available in well-known browsers such as Opera and MozillaFirefox for several decades.
