For the most part I’ve met iOS updates with the mindset, “I’ll just be happy if it’s stable”. Because when iPadOS 13 landed the features were much needed but the stability was crapola on my then young iPad Pro. Recent releases have thankfully been less hazardous and iPadOS 14 would become pretty stable for me.
Upgrading to iPadOS 15 thus far has passed the stability requirement. Plus for the first time it feels like new features have landed in a polished form. Running multiple applications using split screen, slide over, and the would probably confuse non nerdy users multiple instances thing, now work really damn well. iPadOS 15’s the best implementation of such things I’ve had since Samsung started to screw over theirs in favor of Googly multitasking and focusing on DeX.
So while I honestly could have cared less about the multitasking features earlier on, beyond slide over being a common offender in my iPadOS 13 instability, iPadOS 15 actually makes me view the fancy split screening stuff as a feature I can use.
