After much deliberation, I finally settled on the 12.9". I still can't believe I had such a hard time making a decision. Initially I purchased the 11" and vowed I wouldn't even look at the 12.9", that plan quickly derailed. Picked up the 12.9" and have been going back and forth for the last week. I have boxed up the 12.9" and 11" multiple times. Finally decided that the 12.9" is the one for me.
The same happened to me. I even posted on this thread that I was keeping the 11 and not looking back! I jumped all the way in, using the 11 for several hours a day, and the more I started using split screen and when I had to type on the screen to send a text and could only see about 25% above the keyboard, I started to re-think things...I went all the way down to the last day for me to return and decided I didn't think it would be a good use of $$$ and the tool that best fit my work style.
I've watched pretty much every 'VS' video I could find on YouTube and to be honest, there are only a couple that actually talk about the practicalities between the sizes. We all know the specs, about the pencil and the keyboards, etc. But nothing that really helped me all that much. It took day to day, actual work to help me decide.
It was not easy. The 11 is a beautiful slab of glass, and I liked the idea of the portability, but at the end of the day, both of these products are very portable. I know, different strokes for different folks and as I said before, you can't go wrong with either one. It comes down to how YOU decide to use them.
Congrats to all those who've made their final decision, and best of luck to those still on the fence...a fence I've hopped way too many times over the past few weeks!
