We’ve seen some pretty wild promotions in our day, but Dell’s latest really has us scratching our heads. Starting today and for a limited time only, you can get Iron Man preloaded on a select Dell laptop or desktop for an additional $20. This is not the Iron Man DVD or Blu-ray disc, but a digital movie file (Windows Media format) pre-loaded onto the system’s hard drive. Currently the three system options are an Inspiron 1525 (starting at $649), an XPS 420 (starting at $899), and an XPS 630 (starting at $1,299).
