I'm kind of surprised by the lack of interest in this size tablet. I downsized my IPP from 12.9 to 11, and I'm much happier with the smaller size overall. There have been very few times where I was drawing and I wanted the larger screen, but honestly, in those times I would have wanted a larger screen than the 12.9 could give me, and that's reason for me to get a larger pen display, not a giant tablet.
Definitely a personal preference thing, but it appears overall you may be in the majority. I have always liked around an 11" size though. My first netbook back in the day was an 11 inch HP iirc. That thing was a workhorse and lasted me a good long time for what it was. I also used to always draw on moleskin sized sketchbooks though back when I did traditional art more, so I guess I'm just used to the smaller size from both sides.
