Apple would not make changes for me specifically. You are right about this. However I did not mean that. I meant general bugs that not affect just me but the general population using iPads. I might be wrong but based on the keynote iPadOS is supposed to bring a lot of features and I am just kind of sensing it would not be that stable in its first version. I would not be surprised if it takes about 2 months or something like that to stabilize that version.
I am not talking about bugs in the new features that iPadOS is supposed to bring. I am talking about regression bugs that might impact my usage. For example I kind of expect changes in the Files app (due to the external devices support). Now Files app is buggy as it is, I would not want to experience even more bugs so I would prefer to wait and see how it behaves. Same for Reminders and Notes apps. I use them enough to not want to experience issues.
I obviously cannot prove my feelings. It is just my Intuition. You might be right that it is not worth the wait but I honestly lose nothing in waiting. There is also the fact that my company issues company iPhones and iPads anyway and because of this we do our internal testing. So at the least I will wait for my company internal tests to pass before upgrading.
