I decided to buy a 10.5. My usage of safari tabs really begs for more than 2GB RAM. The 4GB spec sold me, and safari is a-maz-ing on the 10.5. The device is also fast overall. I can have a ton of tabs open. The processor is clearly a mega-whopper. I have three issues with the 10.5, though. 1) That Apple doesn’t sell the silicone back case is totally ridiculous. I think they stopped selling the silicone back because it’s not conducive to “pro” work, and it facilitates content consumption. Tisk tisk, says Tim Cook at my content consumption. Well Tim, all work and no silicone play (ahem) makes Steve a dull boy. I bought a khomo case instead but it is only about 70% as nice. 2) The speakers are clearly quieter at 10/10 on the 10.5 than 9.7. There is another thread on macrumors about this. Do I need to take my device in? Do we all (who have this issue) need to? 3) I’m not really sold on the 10.5 screen size. For bed time usage, the screen is a bit much in my face. I am sure I would have preferred 10”. If there was a 4GB 9.7 option, I think I might have picked it.
