I have a personal iPad Pro 10.5 and a work-issued MacBook Pro 13. I must say that the portability and versatility of the iPad is very nice, and I have used it as my primary personal computer for the past couple of years. However, there are some MAJOR shortcomings which have often forced me to use my work-issued MacBook Pro (which I do not like to do with personal data):
1. Apps. Even basic functionality which exists in the Mac version of Microsoft Office isn't in the iOS/iPadOS version, which is REALLY stripped down. Same is true for many of the native Apple apps, such as Mail. In addition, I have an audio capture app which I occasionally use on the Mac, and there is no equivalent on the iPad (captures system audio to a file). The iPad versions of Safari and Firefox will still sometimes load the "mobile" or "tablet" versions of web sites, even when set to request desktop versions; this always happens when you use Split Screen. I have a music collection built up over the years (from various sources) on the Mac, but can't figure out how to get this onto the iPad without using a Mac. I cannot rip new CDs, etc. into iTunes on iPadOS, as I haven't yet transferred all of my CD collection to digital files, nor can I see or change the metadata for songs already in iTunes on the iPad. Again, apps are often REALLY stripped down versus their desktop counterparts, or even worse, only exist as front-ends to cloud services which force you to store your data on someone else's system rather than your local iPad.
2. The multitasking interface isn't nearly as easy, efficient, or flexible to work with as macOS, where you can just put multiple windows wherever you want them on the screen, and see everything at once.
3. No traditional file system access. This makes working with files a PAIN, especially when different apps handle file access differently. Most iPadOS apps really aren't file or print-centric; it feels like these capabilities are an afterthought and very basic in function.
4. Lack of a desktop as a place to temporarily put things. If I'm working with screen caps, moving files around, etc. I can put everything on the Desktop and then move it to where I would like using multiple windows. Yes, you might be lucky enough to have your apps permit saving to Files, and do it from there, but the workflow here is not nearly as efficient.
5. Printer support. Basic printing to a printer which supports AirPrint works fine most of the time, but when it doesn't (formatting is off, page which looks fine on print preview outputs differently, etc.) then you're stuck. Print options are minimal compared with macOS, such as the inability to select a custom paper size. I have a HP MFC, and can print from the iPad, but can't fax or scan as I can with the Mac. There is no print job management or status functionality, so if there's a problem after you hit "Print," you're left in the dark.
The iPad is a great portable computer for very basic functionality, but it has a long way to go in order to mirror the very basic functionality of a laptop or desktop. Until iPadOS is more full-featured and flexible, and the apps more mature, it will be very difficult to be a laptop replacement for me. I'm having to do personal work on borrowed laptops enough that I am now looking to purchase a MacBook Pro to use as my primary personal computer.
