I think Gruber’s dead wrong, and folks should try it for a couple months. Leave the Macbook or Win10 laptop at home, and force yourself to rewire your brain into the iPad affordances and apps.

Aside from being able to turn his complaint off:

To turn Multitasking features on or off, go to Settings > Home Screen & Dock > Multitasking then turn off Allow Multiple Apps if you don't want to use Slide Over or Split View.

I think it works fine for business and development consumption and creation, both.

I’ve daily drivered iPad Pro with Apple keyboard for last 3 generations of iPad 12.9”. It started as an experiment to see if we could move employee population over for less support costs, and then became a habit because it’s just too ideal if you’re mobile for travel or even between multiple offices and meetings.

Each new Macbook model, I get nostalgic for MBP days and carry it around for a bit, and then realize too many compromises carrying a laptop compared to carrying or traveling with just the iPad Pro.

I’m on a two week trip right now, with the brand new top of line Macbook Pro 16” with full dev and Adobe setup in my bag. But it only came out of my carry on once in two weeks, and that was a failure.

Tried to display a web demo, some custom diagramming, and a PowerPoint on conference room screen from the laptop. Unable to use the enterprise guest WiFi due to their security proxies, and the hotspot was too slow. Popped the same USB-C HDMI adapter in the iPad, and showed all the content over LTE.

In a room built for Windows world, people struggled, and failed, to get HDMI from their HP or Dell or Lenovo laptops working, via HDMI ports or USB-C ports. Both the Macbook and iPad “just worked” with Apple’s same latest USB-C to HDMI adapter.

With the always on networking, all day battery life, decent choice of text based dev tools including code editors, git clients, and terminals like Blink (mosh) to do git-commit based development/deployment, Citrix and RSA and enterprise VPN, not to mention full O365 and Adobe suites (though I recommend Affinity now), it’s hard to figure out what it is I need the laptop for enough to deal with the PITA of carrying it.

This was not true 10 years ago, but today, iPad Pro can be the sole computing device even for an enterprise technology executive.

Bonus anecdata, I’ve recently noticed the iPad Pro is what’s used by 80% of folks in the board room, even though it’s a Windows based enterprise. Something’s changed.
