Dell Streak / Mini 5 makes a cameo appearance at MTV

It's been a while since we've heard much about the Dell Streak / Mini 5, but it seems like the plus-size phone (or mini-size tablet, whichever you prefer) went on a bit of an undercover media promotion tour last week: Viacom MTV exec Greg Clayman tweeted that it's "amazing," while Rob Enderle brought one to the set of John C. Dvorak's Cranky Geeks and said it would launch for around $300 on contract. What does it all mean? We're assuming it's being shown off in an effort to drum up some content partnerships: we've already heard about tie-ins with Amazon's MP3, video, and Kindle stores, and we'd bet that Dell's also going after newspapers, magazines, and video sites hard in an effort to push back at the iPad -- especially since the company is planning to bring out an entire "family of tablets" in the future. Or... it's nothing at all, and AT&T is going to completely wreck this thing before it launches, like it did with the Aero. Dreams or nightmares, the choice is yours.
