I normally sell my current iPad and then upgrade to the next version. For my use I think I want the 12.9 this go around as the 9.7 was too cramped for multitasking. My concern is I see way more 12.9 Pros going unsold this year and it makes me think because the 9.7 is the most popular size. I feel this will be the same for the 10.5 Any feel the same when they decided on which one or am I being ridiculous in thinking about resale at this point? Thanks for any feedback.
