Microsoft’s Worldwide Partner Conference kicked today in Washington D.C. and Steve Ballmer has already made it a point to announce that the company is “hardcore” about tablets.

“We want to give you a consumer-oriented device, but a device that fits and is manageable with today’s enterprise IT solutions,” Ballmer said. “They’ll come with keyboards, they’ll come without keyboards, they’ll be dockable, there’ll be many form factors, many price points, many sizes. But they will run Windows 7,” he added.

Twitter user @Javiergc posted the screenshot below, highlighting hardware partners including Asus, Dell, Samsung, and Toshiba and others.

Ballmer says he expects to sell 350 million Windows units this year. Since Apple sold more than three million iPads in the first 80 days after hitting the market, Microsoft has some catching up to do.
