I went from PC desktop to PC laptop to iPad….and, since 2017, have remained iPad only.
Basic stuff, obviously, but also tons of pdfs with my nerd old-school rpg (D&D and more)… also, more importantly, I’ve been using just and only base model (except for storage) iPads to do full-on music creation/production with multiple apps, etc for years. Never once needed an iPad Air nor an iPad Pro.
Also, as I’ve transferred everything from iPad to iPad, and saving tons of docs, samples, music files, music production tools, etc….. I’ve used a total of 52GB…..over 7 years!
My “basic” 2020 iPad can still do everything and anything I throw at it.
There are absolutely and inarguable cases wherein ya need more, perhaps a whole lot more….but, don’t be fooled into imagining ya need the latest and greatest iPad.
