We’re posting all the interviews from the sixth D: All Things Digital conference that took place in late May.

Unfortunately, due to issues too complicated to go into, we have to post all the D6 interviews in several 15-minute parts (I know, I know).

But–as many readers have requested–they will all be available in their entirety in this column.

Here’s an interview that Walt Mossberg did with Michael Dell, the founder of the once-high-flying computer company who has returned as its CEO. Dell was forced to resume the role in 2007, after changing market conditions caused the company to falter and competition from other makers of personal computers, such as Apple, Hewlett-Packard and Sony, have increased.

The video of the interview is in three parts, which I will be posting this week.

In this first part, Dell talks about the previous conference appearance by former Dell CEO Kevin Rollins and his contention that research and development was unneeded, how Dell stumbled and how it is trying to right itself and a new focus on fashion, design and distribution.
