You're likely still recovering from the revelation just a couple of weeks ago that the iPad Pro is now a computer.
Apple was insisting it's incredible what its tablet can now do.
Microsoft has decided to respond to this claim. I translate its response: "Chuckle. Chuckle. Chuckle. Giggle. Snort."
Redmond on Tuesday released an ad mockingthe notion that the iPad Pro and the Surface Pro 4 can be said to be similar. Or that the iPad Pro can claim to be a computer.
Here we have Microsoft's Cortana retaining her cordial relations with Apple's Siri.
"Hi, Siri. What's the party for?" asks Cortana politely.
Siri seems to be celebrating, you see.
"I just got a keyboard," replies Siri, referring to her iPad Pro. "I'm a computer now. Like you."
Cortana thinks herself a touch superior. She wonders whether the iPad Pro has a little more power than it used to. She wonders whether it's running full Office, not merely the app version.
From there the chuckles and insults flow.
Apple didn't immediately respond to a request for comment. I did, however, ask Siri on my own iPhone what she thought of the Surface Pro 4.
"I'm afraid I can't answer that," she said. A touch coy, I thought.
My colleague Dan Ackerman, in reviewing the Surface Pro 4, mused that Microsoft does actually charge you extra for its keyboard. He still described it as "a trailblazer."
I'm not entirely sure that any company has quite worked out what a computer is anymore.
There are so many different needs and so many different categories of devices that everything is a computer and nothing quite is.
This will likely only be solved when we have computers implanted in our brains. Just imagine how much easier life will be then.
