In a sign that proves just how much the general public dislikes Windows Vista, Dell has announced that they have postponed their kill date for Windows XP from today until June 26th. Interested consumers can still purchase an XP-laden Dell system until 7 AM Eastern time on the 26th, after which point Vista will be your only Microsoft OS option. The extension only applies to three versions of Dell’s Inspiron 530, as well as the XPS 630. If you’ve been thinking about a grabbing a Dell, and hate Windows Vista, we suggest you head on over to the company’s site quickly, as time is most certainly running out.
