Let me save you the trouble instead of eating the BS prices posted in this article... obviously only serving to be a sales pitch from Apple.

A functional 4K ready Mac Mini (without monitor) will set you back 4.000 dollars.

That will give you:
3.2ghz 6-core, i7 with hyperthreading, 64gb ram and 2tb harddrive.

If you settle for spending only 799 dollars you'll get this weak ass piece of crap:

3.6 quad core, i3 NO hyperthreading, 8gb ram and 128gb of harddrive.

I don't even know what I'd use that setup for....... so as for "wooing the pros", what a load of BS.
My current pc setup which is pretty in-expensive to make now, is cheaper and more powerful than this.
Seriously, why do people keep falling on their arse over Apples announcements? I mean, I sit by an iMac at work, but I'd rather be working on my own pc.
There is no justification for the pricing of these products...none.

Can anyone share some info on what suitcase he used to carry spare batteries in?

Would be more fitting calling it overcast window light.... Title is misleading :)

"Program" as in a course?

Did he atleast say why he had the idea that you could only edit in FCPX?

Seems pretty stupid to just demand without saying why.

Of the three I would say FCP is the weakest. And the PR / AE setup will loose ground once Resolve 15 is out of beta. It will incorporate Fusion in this release and the editing suite is powerful enough now for most people's use.

I have already left PR behind. It doesn't make sense anymore, and it's colorgrading tools are weak compared to DR.

So... if you are indeed going edit it from start to finish and export and deliver yourself, I see no sound reason that your client "demands" you use a specific tool. Your best tool is the one that makes you works the fastest without the fewest hickups.

I would politely tell my own client that while they may have used FCPX themselves, I will not.

Worth mentioning... you need a US bank account to sign up for this.
