Well, I've largely kept quiet about my buyers remorse over the 10.5. Buyers remorse is probably the wrong term, since I really did like the 10.5, but the idea of the 12.9 model kept nagging me, like a mosquito bite that wouldn't stop. I've let it me known in a handful of posts that I was waffling between the two models, but as time went on, and my 14 days of ownership, turned into 21, 28, etc etc, I looked to be content with my purchase and I largely was. I remember when the Apple first announced the 12.9 and I almost bought one then, but I held off. When the 10.5 mode hit the streets, I thought now was the time. I was content with the purchase until I came to the apple store to pick it up, and it in the apple store, the 10.5 looked diminutive. I thought I made a mistake, but I kept my mouth closed. I should have then opted for the larger model, but I didn't. A month and a half later for giggles, I packed up my iPad Pro, drove to my local apple store and they allowed me to exchange my 10.5 for the 12.9. I figured what's the worst that can happen, I walk out with my 10.5 again and as I said, it was a fabulous tablet. To be honest, I was completely dumbfounded when they said they would allow me to exchange the 10.5, for the 12.9, even though I bought it back in June. Yes, I was hoping something positive could come about it, why else would I show up at the apple store with my iPad Pro boxed up, but I was resigned to the fact, that I had missed my window of opportunity. Yet the manager at the Apple store allowed me to "trade up" Kudos to Apple for such a great customer service move, words cannot really express how grateful I am. They had no reason to help me, but they did. I'm very happy with my purchase, the screen is gorgeous, the iPad is FREAKING HUGE but its I wanted. Some of the things I liked about the 10.5, i.e., its mobility, will need to be accommodated with the larger form factor. I'm wondering if I'll suffer any sort of hand/arm fatigue from using it upright (as opposed to a desk), but overall the screen is the size that I think will enhance my enjoyment. tl;dr I kept quiet about my desire for 12.9, when I shouldn't. Apple's top notch service allowed me to upgrade when I didn't deserve it.
