Ballmer, who bought the team for $2 billion earlier this year, stepped down as CEO of Microsoft in February after 14 years in the role. He owns four percent of the company's shares, worth nearly $16 billion.
He told Reuters he plans to have the Clippers drop Apple for Microsoft.
"Most of the Clippers on are [sic] Windows, some of the players and coaches are not," Ballmer said.
"And Doc kind of knows that’s a project. It's one of the first things he said to me: 'We are probably going to get rid of these iPads, aren’t we?' And I said, 'Yeah, we probably are.' But I promised we would do it during the off season."
The Clippers finished 57-25 last season before losing to the Oklahoma City Thunder in the second round of the playoffs.
