I think I have only used Inkarnate on Safari on my IPP. What features am I missing? It seems to work fine for me.
But, aside from that, I generally agree. The Surface line and any Windows experience in general, has not been great, or even good as a tablet. iPadOS for the most part has. My main gripe with iPadOS is the file system and how hard Apple makes it for anything to use any cloud storage other than iCloud. For instance, I do a lot of my finishing work for my art in Clip Studio Paint, and I have a OneDrive account, which CSP technically supports. Anytime I save files from CSP to OneDrive though, sometimes the program just crashes and I lose my work. This is partially on CSP, but mostly because Apple makes it difficult to program for this. CSP will fix it, then I’ll get a new IOS update, and it will break again. CSP will fix it, and IOS will update and so on and so on, for 3 years now. So now, I have to save a copy on my iPad storage, (which doesn’t allow me to save in any folder I want, only giving me a certain number of folders to save my art in), and then once I’m sure I have my work saved, attempt to save a copy on OneDrive as well and just hope it works.
As far as MacOS goes with the file system, it’s a similar amount of bias that makes it more annoying to me than Windows. OneDrive is available, but it’s not well integrated. With Windows it seems you can use any cloud storage you want easily and it will integrate easily, but with MacOS, if it’s not iCloud, it’s not going to be easy. And sure, I could pay for iCloud and get my terabyte of storage there to save me the headache, but by paying for MS Office Suite for the same price, I get the same terabyte AND full Office Suite, which my wife uses fairly regularly. But the file system on MacOS is a fairly mild complaint compared to iPadOS, which is borderline atrocious.
All this to say, if the iPad could be both, that would be awesome. But if the rumors are true that it’s going to be MacOS “lite” on the upcoming IPPs, then I am very cautious on what that could mean. Because if the file system is closer to iPadOS than MacOS, and I still have the same problems with CSP that I currently have been dealing with, then my 2 device solution will still be much better than a single crippled device. Right now I can at least AirDrop with ease to my MBP and take advantage of its full file system when I need it.
