I had a time when I was involved with startups of various kinds (sometimes West Coast, sometimes Research Triangle Park, more often NYC or upstate.) I was a Windows user in a MacOS world and the most important accessory I packed was whatever I needed to hook up to mini-Displayport.
For me the magic of tablets is that they are low cost, so I'm not afraid of losing or breaking them. They don't become a nexus of further expensive consumption: adding an expensive case, particularly one with a an expensive and special purpose keyboard, just takes something sleek and easy to handle and makes it klunky and awkward.
Go to a hackathon? Get any Bluetooth keyboard and mouse and a $5 plastic clip from Amazon Basics and you've got something sleeker and more stylish than any Macbook or gaming laptop with which you can connect to a powerful desktop computer or a cloud instance that is anywhere from 50 cents to $4 an hour depending on your thirst for power.
I started out with a B&N Nook, then Amazon Fire Tablets (amazing value for the money), then iPads, I had bad luck with my last iPad (either lost or stolen) and figured I'd use an old Samsung Galaxy tablet I had kicking around. Every time I got an iPad I looked at my options, hypothetically I thought I might like the Pro but a new Pro is crazy expensive (I couldn't afford to break or lose it) and an old Pro in my price range is old technology.
(Note I'm a little weird because I've never owned a smartphone with a plan. Carriers choose not to serve my valley, why should I get an expensive plan? My data plan is WiFi, and my phone plan is Skype)
The Pro, like the AVP, also seems hobbled by Apple's short-sightedness. A device that expensive, with hardware as capable, should be able to do 100% of what a MacBook can do. It should be able to completely outdo the Microsoft Surface, but it doesn't.
This may be true globally, but isn't necessarily reflective of actual market share for the markets targeted.
If your startup is selling to people in say, United States, Canada, the United Kingdom, Australia or New Zealand, then Mac marketshare is 20% to 30% of all computer usage (depending on which nation, how you count, and whose measurements you use, etc).
