Honestly
@temna and
@ZBoater, you both have some good points. The ipad has certainly become more capable than it has in the past. I actually did replace my macbook with an ipad 3 when those first came out. I did it for about 5 months, but there was so much that was cumbersome that I couldn't deal with it any longer. Looking back, things have become a lot easier to make that transition, but there are some basic things that make it difficult.
File transfers and firmware upgrades are one example of something that makes it difficult. The good news is that a lot of these things can be done (well, not the firmware quite yet). The bad news is that these things are still cumbersome.
Here is an example. I have a local makerspace near me that I have gone to to 3d print. If I brought my laptop, I can simply put my 3d gcode files on an sd card and pop it into the machine or I can connect via usb directly and print. If I brought my ipad, i would have to export the files to a cloud drive, find a nearby computer, visit the cloud storage site, download and then export for print or connect via usb. In this case you're still dependant on a main computer! I don' t know if these external hard drives and app combos like filebrowser will provide this functionality, so pardon me. Printing photos at a friend's or family member's house who doesn't have and airprint capable printer provides the same dilemma.
The biggest problem comes down to native support. PCs have long had native support for various connection options, filebrowsing, etc... The ipad doesn't natively support some of these very basic and often used functions. As a result, various workarounds have had to be invented. This has increased the friction of getting things done in some regards, which is counter to what the advancement of PCs is all about.
I believe Apple could solve a good deal of these workarounds with additions to iOS. I am hopeful that they will as well as they seem to be placing decent bets on the ipad pro as a primary computing platform.
One more note: I love my ipad Pro and would love to ditch the PC for it. There are a lot of things that I enjoy doing far more on my ipad than my laptop.
