It’s not about having a machine labelled pro to do a professional task, or feel professional. It’s about having a device that is designed to do what you need it to do well, professional or not. But seeing as most people around here are professionals in some capacity, let’s look at it from their perspective, and that is where I take issue with in your iPhone/MacBook Pro comparison.
Yes, an iPhone excels at photography. It really does, but that is pretty much where it’s professional use ends, beyond being a damn good business phone. For example, what if you need to then edit those photos... your work flow is cut short short by limited capability in a mobile version of a desktop app. Then looking at some other professional tasks, even the most basic, writing, the iPhone is not a practical device for doing that beyond some quick edits on the go. And like others have pointed out, you have no hope if you want to do something that requires a multi-file setup like web development or programming. In short, just because a device can do some tasks well, it doesn’t make it the right device to do them on, and there is no shame in using multiple devices to achieve your workflow.
And no, you don’t need a MacBook Pro for many professional workflows, a £250 chromebook is more than enough for pros in some fields. But then there are also some pros that genuinely do need that additional power combined with mobility that Apple just isn’t offering right now. Is that me, no. Is it you, doesn’t sound like it. But that doesn’t mean the need doesn’t exist.
So, you are telling me you need a MacBook Pro for word processing?
Seriously, your credibility ends there. Because no matter how you look at it, a MacBook Pro can only go so far itself for content creation. That same photographer I mentioned, doesn't even use a MacBook Pro as his main editing station. He travels with a iMac Pro for that. Macrumors recently highlighted it in an article.
My comparison wasn't about one necessarily being better than the other, but the reality is, prior to June 29th 2007, a large group of Mac users would spend money on the very best just to do some mundane things, even if Apple offered entry level models for their needs. This included the things I mentioned.
I remember in 2007 when I was doing vocational studies, a student attending the same institution had a MacBook Pro. She really had no use for it beyond running Peach Tree accounting and Microsoft Word 2007 in Boot Camp. But she had a top of the line MacBook Pro because her husband bought it for her.
I remember earlier that year too, I use to hang out at a local print shop. A guy working there visiting from Mexico was using some old 1998 iMac G3's to run Photoshop and Illustrator CS1 on 10.3 to create amazing T-shirt logos and making a killing out of it. He made so much money off those Macs, he was able to go back to Mexico and start his own business.
Now, a iMac G3 in 2007 was not state of the art, but it was doing really professional work. Another memory from that time happened when I was invited to visit a guy at a local PC repair shop to check out his MacBook Pro. When I checked out what he had on it, just a bunch of photos and an empty Finder. Its obvious this guy wasn't using it for much.
Its just like how many Pro users are countering that Apple needs to have a highend Mac Pro modular workstation in order for professionals to live. Yet, they have pretty much migrated to a specced out iMac or even the recent iMac Pro. If you check out over at the Mac Pro forums, it has pretty much quite down.
It even goes back to the Mini computer vs the Workstation vs the PC itself. Eventually the Mini and Workstation became a niche because a PC could do most of what those high end computers did for really cheap.
Is that me, no. Is it you, doesn’t sound like it. But that doesn’t mean the need doesn’t exist.
Which is exactly what I said, but it looks like you just figured it out while writing everything you said. Not everyone needs a MacBook Pro and many are getting the job done across a variety of devices and platforms including the iPhone. Its same case of some needing something more powerful than a MacBook Pro so they choose a Dell or HP.
