You heard it here first: all MIX07 attendees will receive a free copy of Windows Vista Ultimate, the one with the most checkboxes on the chart (how else do you think we’d pick the one to give out?). Yes, this is the full edition, not an upgrade. We’re talking a suggested retail value of $399 USD! And guess what? Our Windows Vista Family Discount applies too. That means that—if you qualify—you can purchase up to two household PC upgrades to Windows Vista Home Premium for only $49.99 USD each! All told, that’s a value somewhere around $617 USD. This might be the closest to a “sure thing” you’ll ever see in Vegas.
