Dell recently used its mailing list to send out an email promoting the Streak and some of its other products. The message carried a subject line of "The future in the palm of your hand" and was therefore very Streak-centric, featuring the photo and info you see here at the top of the email and another "We fit the whole world into a 5-inch screen" banner with a photo and a one-line description ("Introducing the NEW Dell Streak, the mobile entertainment, social connection and navigation device") at the bottom.
Also at the top, though in a much smaller font that makes it easy to miss and mistake for part of the header, is an offer for 25% off all docking stations for the Streak when purchased in the same order as the Streak itself. What isn't clear from the email is whether both docks (car and home) have to be purchased, which is how the "25% off car & home docks" discount that expires on Monday works on the site.
Thanks to everyone who sent this in!
