Hi Phil & LOTR
As a windows XP & PC user I would just like to make a very basic comment and that is not all upgrades are beneficial or in the best interest of the end user
I have found that I can get the things I need done using my ancient (7 years old) PC running even older software, e.g. MS Word 97. And I am not the least bit tempted to upgrade to the latest software loaded with features I will never use, or even worse minus features that I do use
In short, I now will only upgrade an application if there are clear benefits for me, the end user, and not because the makers want me to

PS. I do not include security upgrades/patches in my personal "cautious upgrade" policy
