I have had the 12.9” gen 2 since June 19th. Originally I would have told you that I was ok with the large size. I am a small female but I hated the too small Mini I had for a short time so when updating from my 9.7”, I wanted to go big. I have enjoyed the top row numbers on the 12.9” but lately I am just so tired of this large heavy size, I am wishing I had the 10.5 instead.
I mostly use this big 12.9” in my lap for mindless consumption, no movies, no games. I do have an Apple Pencil, Affinity Photo for the iPad, 256gb, shoot Raw photos on my camera. I thought at the time of order, oh I really need 256gb but here it is January and I have less than 15gb used. I do just enough photography to stick with the Pro/Pencil but I could save some money and be fine with 64gb.
I say all this because I am seriously considering getting a 10.5, my 18 y.o. Grandaughter is so wanting this 12.9” ipad. Since she is on her way to getting an athletic scholarship to a top college, I try to do whatever I can for her.
