Everything is easier.

I think they thought something like this:

The card reader. Noot for a professional? After all, it is so convenient to put the software from the manufacturer, create a Wi-Fi point and transmit photos through it. And yes, disable these memory extensions via SD cards.
Remove the USB. Noot for a professional? New devices with full USB no longer exist.
and HDMI. Noot for a professional? Why do some professionals connect something to the most universal connector at the moment?
Food with magnets. Noot for a professional? So he will always stand on the table and not move. This is a laptop!
The F key. Noot for a professional? Seriously, who is using them? Better we put the screen there, and move the entire keyboard down just to remind people that there could fit another string of keys.
The battery. Noot for a professional? Why increase autonomy? Let’s make it thinner.

People with one twist have only one parameter. On the one hand "hard" and on the other hand "not cool". Such an abstract and vague "crute" consisting only of some unfathomable scattering in which only its width is measured. The real needs of the target audience are too complicated, from this head bo-bo. So I thought something like this:

We’re doing it for profs!
Profit is cool, heh. he he. he he.
We take what is cool and add it to the note.
Yes the bacon.
Thin is cool! Magnets are cool! A small screen is great!
