It's no secret why Dell's struggling so badly it just took a $2b loan from Microsoft and bought itself back from shareholders to become a private company: after more than a decade of effort, the company never figured out what consumers actually want beyond low prices, or why they might want it.

You might laugh, but it's true — a look back at Dell's biggest attempts to crack the consumer market and compete with Apple over the past 10 years reveals an embarrassing series of missteps, mistakes, and flat-out bad software, culminating in a flurry of poorly-executed mobile devices in 2010 that sealed the company's fate. As the world went mobile, Dell stopped moving. "We're no longer a PC company," said Dell VP Brad Anderson last year. "We're an IT company." We'll see how Dell manages this new chapter of its life in the months ahead — but for now, let's just slide on down Dell's sad little spiral together.
