Microsoft today launched a new commercial for its Surface Pro 4, comparing the tablet computer to Apple's iPad Pro and Smart Keyboard. The ad -- titled "What's a Computer? Just ask Cortana" -- was posted on YouTube today with a description claiming that "just because you call something a computer doesn’t mean it fits the description." The new ad is clearly targeting Apple's new "What's a Computer?" ad campaign and "Super. Computer." slogan for the iPad Pro.

The ad centers around a party that Siri is holding for its new Smart Keyboard, telling the Surface Pro 4 "I'm a computer now, like you." The Surface Pro 4 responds, asking if Apple's tablet has an Intel Core i7 processor, full access to Microsoft Office beyond the mobile app versions, a trackpad, and external port options. Siri responds with, "Like I said, I just got a keyboard."

The ad ends with the tagline, "Surface does more. Just like you." The new ad today follows a similar anti-Apple theme of many Microsoft ads, which have previously focused on comparing the Surface Book and MacBook , and Windows 10 and OS X . For Christmas last year, the company released a more peaceful ad that centered around a group of Microsoft Store employees singing seasonal carols outside of an Apple Store.

The Surface Pro 4 starts at $899 for 128GB of internal storage and 4GB of RAM, and going up to as much as $1,799 for 256GB of internal storage and 16GB of RAM. Comparatively, the 12.9-inch iPad Pro starts at a smaller $799 for 32GB and maxes out at $1,099 for 256GB, with all models including 4GB of RAM.
