Microsoft and Cortana respond to Apple's "What's a computer?" ad
Placed side-by-side with each other, the tablets have a conversation voiced by their virtual personal assistants. That would be Siri for the iPad Pro and Cortana for the Surface Pro 4. Siri says that there is a party going on because the iPad Pro has a keyboard. The accessory turns the tablet into a computer, according to Apple's virtual voice activated assistant, just like the Surface Pro 4 with its optional Type Cover. But Cortana notes that the Surface Pro 4 runs the full version of Office, not just the app. And with the optional keyboard in place, the Surface Pro 4 has a trackpad which is lacking from the iPad Pro's Smart Keyboard.
And the end of the 30-second spot, Siri comes to the realization that having a party to celebrate its keyboard is not a good idea after all. What is implied in the ad is that the Surface Pro 4 is more of a computer than the iPad Pro is. You can check out both ads by clicking on the videos below.
