Yeah for sure if there was a specific need that the storage wasn’t meeting, or making it very cumbersome to manage, then I would have upgraded just for storage too. But in my case, there were always manageable workarounds.
I was just surprised about that price because I didn’t remember it ever being that high for the second gen, even at full price with tax and everything (unless you add the pencil and/or smart keyboard). Anyway, it can definitely be worth paying that much if the device fills a big need/want. I happily paid full price for my first gen 12.9. It was my first iPad. I had no interest in iPads before then because they were not good digital sketchbooks—too small and no good stylus. When the 12.9 and Apple Pencil was announced, I almost soiled myself. I didn’t get one at launch though, I think maybe because I couldn’t afford it, can’t remember. I didn’t get one until they upped the storage to 256gb, which was a nice bonus. I was planning to hold onto it until it became unusable or until there was a new must-have feature. But when I saw Apple did away with the big bezels and Touch ID (features I prefer), I decided to get the second gen just for extra longevity. As it wasn’t really a functional upgrade, I was totally fine waiting for a sale.
After my first gen 12.9 I also got an iPad mini for casual consumption. I like owning two iPads as well. Both are uniquely good at their tasks and integral.
