With so many people reporting trouble in learning to handle Vista - or plainly lack of time to learn all over again what you've rubbed in the ways to do in XP - I'm feeling instinctive sympathy for this petition to Microsoft:

Microsoft originally planned to drop selling XP by retail or delivering updates and patches for it at New Year, three months ago. They have extended the time limit to June 30, 2008. Buying a copy of xp with a new machine has already been blocked for some time, except for some corporate customers buying HP and Dell computers.

XP has proved a very supple and viable system since it was released in 2001 and Microsoft don't really have that much to lose by keeping it available. A big Vista service pack was released this week, and a new post-Vista build is already on the horizon anyway (to be released in 2011?) so hopefully this petition may put some pressure on them to keep XP legit and updatable. Sign your name and keep some watch on what is happening!
