It’s been awhile since Microsoft mocked Apple in a commercial, but the Redmond tech giant is back at it again.

Microsoft posted a new ad on Tuesday that takes aim at Apple’s iPad Pro, claiming that the device can’t be described as a “computer” — unlike the Surface Pro 4.

The 30-second ad, which features Apple’s Siri and Microsoft’s Cortana “talking” to one another, kicks off with Siri telling Cortana that she “just got a keyboard” and that “I’m a computer now, like you.”

“So you have more power, like an Intel Core i7 processor?” Cortana responds.

“Like I said, I just got a keyboard,” Siri says.

Here’s the video description, which includes a link to Microsoft’s comparison page:

Just because you call something a computer doesn’t mean it fits the description. Cortana knows that the Surface Pro 4, with its powerful Intel Core processor, detachable keyboard with real keys and a trackpad, pen, touchscreen, full Office and external ports fits the description. Everything else is just late to the party.

The ad is a response to Apple’s recent “What’s a Computer” spot for the iPad Pro that has garnered more than one million views on YouTube and aired more than 700 times on national television since debuting Aug. 1.

The commercial has a similar vibe to Microsoft previous ads in 2013 and 2014 touting products like the Surface and Cortana, from “Crowded” to  “Head to Head” to “Power” to “Groundhog Day” to “Lost” to “Remind Me.”

It’s worth noting that when Apple debuted the iPad Pro at a press event this past September, Microsoft Office executive Kirk Koenigsbauer appeared on stage, showing the capabilities of the new Apple tablet as demonstrated with a version of Office for the iPad.
