In case you were worried that your beloved Windows XP was going high-tail it out of here like the Dodo, have no fear: as long as your buying super lower power mobile machines it should continue to be available until June 30, 2010.
Redmond (WA) – Microsoft has announced that it plans to extend its support of Windows XP, its nearly seven-year-old operating system, because many computers in the market today are simply unable to run Windows Vista.

With the release of Vista early last year, Microsoft had planned to stop selling XP on June 30, 2008.  Microsoft has decided to push that back because of what it calls a rise in the number of ultra low cost PCs.

Microsoft XP launched in October of 2001 and since then has become the best-selling operating system ever.  So when Windows Vista came out, it was difficult to convince people to upgrade their system.  Computer illiterate and tech enthusiasts alike were too comfortable with XP.  There were also legendary problems with some programs not working on Vista, though many of those have now been fixed.
