Earlier this week, I made a case for why Dell ( DELL ) should Buy BlackBerry (BBRY). BlackBerry investors weren't too pleased - feeling that they were "above Dell." But today, they're singing a different tune - at least they should, given that BlackBerry shares have now fallen below Dell's. While I once felt that Dell would be strengthened by acquiring BlackBerry's assets, I'm not feeling that same way today. In fact, I'm now realizing that BlackBerry's best chance of survival is to dismiss the idea that it can ever compete in this smartphone space. The game's over. And investors that think otherwise are just fooling themselves. The more things change… The company was left for dead after it had gotten beaten-up and bruised by Apple ( AAPL ) iPhone dominance. While I'm more than willing to give BlackBerry credit for its resuscitation after falling to a low of $6 last summer, I just don't believe the company possesses the "wow" factor or the management needed to thrive in the mobile space.
