Ahh bummer... I'm currently using iPad Pro 10.5, and seeing it being almost exclusively a content consumption device (your typical YouTube, internet surgfing, ebook reading) I started to feel this common itch to get the Mini as it would be lighter and more portable around the house and even commute.
But seeing often reloads on my 10.5 with 4 gb of ram I begin to question my idea. I don't use my iPad for anything demanding but still, I would love to have some substantial upgrade over what I have currently. Yes Mini has modern SoC which should make everything run smooth as butter, but 4 gb... iPhone 12 Pro with 6gb runs me circles, I hoped to get similar performance in a bit bigger package. I'll probably wait and see the reviews because I would really love to get this mini and give my old 10.5 to my relatives.
