So you don't think it was inappropriate in a professional setting to make women, which the company goes out of its way to actually attempt to encourage into the industry (they have a specific site for encouragement of women in technology on their official site: http://content.dell.com/us/en/business/women-powering-busine... ), feel like the only thing they're good for is being the butt of jokes?

Wow. For the record, I would, as a white person, feel similarly uncomfortable and disgusted by racist jokes in any setting really. It's one thing to make fun about yourself, it's another to poke fun at others' expense in an unkind manner.
