Did I understand correctly that you still have the 10.5“? In that case, you don’t need to upgrade to the 11“.
I don’t know, it‘s really a pleasure having both devices, besides that bad feeling to have wasted money because of inability to make a decision. But they really have different use cases.
It‘s true, the 11“ is ultra portable. Especially I can‘t see myself boarding a plane with the 12.9“, except maybe on a long distance flight, but for short distances on cheap planes, the tray tables are not even big enough. I already had problems with the 11“ on my last flight.
Also, one bonus of the 11/10.5“ is the keyboard really. I feel like I can type even faster on the smaller keyboard because the keys are so close to each other, I can just fly over them.
I really don‘t feel like taking the 12.9“ out of my backpack at home, while at work I dont feel like using the 11“ on the desk... Argh!
