Returned my 10.5 for a 12.9 about 2 weeks ago. I'm so glad I did and don't regret it one bit. I love the larger screen its better for my eyes and multitasking. The speakers are louder and I'm getting amazing battery life (19-20 hours). At first I was concerned about the size and the weight. I use either the Smart Cover or the Smart Keyboard as a stand about 90% of the time. When I upgraded from the 9.7 pro to the 10.5 I just didn't find it to be big enough for me. Now when I try or see the 10.5 in stores it feels like I'm using the iPad mini. Another concern of mine was being able to get stock in store. After a few days of trying I was finally able to get one in store.
