Define workarounds. iPadOS worked well for me as a productivity device even three revisions ago, so I legitimately don’t understand when people describe it as hampered. The way I see it, the only difference is that you can’t do the same things in exactly the same ways. But that’s true of Mac vs Windows vs Linux vs Android. What kind of workflows are you trying to do that require workarounds, and what kinds of workarounds are you doing? I genuinely want to know.
I'll bite without any snark. Here's my workflow that I would LOVE to simplify.
I'm a fashion photographer. I use CaptureOne as it's far superior to Lightroom for MY needs. On-location shoots, I bring a 2019 13 "MBP. Worst Mac I've ever owned for reasons I'll skip for the sake of answering your workflow question. After the shoot, I transfer with an external drive to my 2010 MacPro with Dual 2.4 Xeon, 40GB ram, RTX570. CP1 works great on this machine. I have five internal hard drives for 9.5TB of space. Boot, Scratch, Long Term Storage, Clone Long Term Storage, and a Time Machine for the Boot and Scratch drive. The MP is getting old, but as a business owner, it's bulletproof reliable. And that is more important than a few seconds faster export. But the thing weighs 50 LBS and SUCKS to drag to a location shoot because I trust it more than the MBP.
I also trade currencies with the MetaTrader4 platform. Again, it's old but an industry standard. TradingView is great, but I found some limitations working with it through my broker.
So, what would my dream machine be? A 12.9" iPadPro that is amazing on set. I can tether into it from my camera and add an external monitor if needed (very common) and an external drive at the same time for clients to take after the shoot. I need a hub, but those are now supported. Stop at a coffee shop after the shoot and place a trade through desktop-class MT4. Get home and dock the iPadPro and use my monthly color-calibrated external monitor and all those external drives.
Here's why non of this works with my 2018 iPad Pro.
CaptureOne doesn't have an iPadOS app. Interesting things ahead with the beta, but no announcement on an app.
MT4 does have an iPad app, but it's far from the full desktop version.
iPad doesn't have full external monitor support.
No external monitor color profiles
I have lots of drives and need flexibility as someone who creates a lot of content for clients.
So the problem is that the software that's vital for my business as a PRO creator isn't available for the iPad. And I'm the target market! Now, you could argue that's a problem on the software side, and I'd tend to agree. But things like access to RAID drives and full external monitor support and color calibration of those monitors, and complete multitasking and file management aren't there yet on iPadOS.
Dropping ~2k on an iPad would be fine if I could sell the MBP and MP, get an external HD enclosure, and run EVERYTHING off that one machine. So I'm looking forward to an M1 something. However, I can't justify it beyond selling the MPB and getting an M1MBP and waiting until my ideal setup of one powerful device on the go and the same device with a dock and all the "desktop stuff" that's need for the workstation. Now a 16" M1MBP might be that solution, but I prefer the smaller form factor for location work.
While I think I have some specific needs that don't work in today's iPadOS environment, I know I can't be alone. I'm looking forward to Apple truly delivering the all-in-one for the pro like me that is portable, insane battery life, powerful, isn't an intel toaster oven, and can handle all the old-style workstation desktop-class hoops we professional creators have to jump through.
Sorry for the incredibly long post; I hope that puts it into perspective that there are just a FEW things it can't do, but those things are non-negotiable.
