For me, rather than having a main iPad and a docked “desk iPad”, which I’d find a bit redundant, my ideal setup is an iPad (which I currently have docked but when I need it, I carry it with me to whenever I need to work with it) and a Mac mini as a desk computer, that I’ll soon get. I’m waiting just to see if they release an M5 model that includes Thunderbolt 5 like in the Pro version, but I still don’t know which one I’ll end up buying.
Both of them connected to a 4K monitor. I currently have my awesome M2 iPad Pro attached to an external monitor, and use it as my main computer, but I’m really missing the macOS experience. I could “make do” with the iPad Pro alone, but… I don’t know, I like the look and feel of macOS and the idea that I can push it’s limits without the fear of damaging the battery because of the heat of the SoC.
But for me, a Mac mini + iPad Pro + PS5 Pro + 4K display is the ideal setup. Mac mini for intensive compute tasks, heavy multitasking and versatility, iPad Pro for mobile productivity, PS5 Pro to enjoy gaming, and the 4K display to enjoy all three devices on my desk. And I’m halfway there. I know about the macOS 4K scaling issue, I don’t care about it, I’ve tried it in the past and it looks great for me.
