Like the specs on this, but a little pricey
This tablet has good specs and a decent aspect ratio (unlike the terrible 4:3 ratio on the Nexus 9, which was a dealbreaker for me), but - like the Nexus 9 - it seems somewhat overpriced to me. It costs the same price as the Galaxy Tab S 10.5" (thanks to a cashback offer), but has nowhere near as good a display.
The Tab S 8.4" and 10.5" models can run CyanogenMod - which is my #1 requirement of *any* Android device so I have no bloatware and frequent updates - and it looks like work has started on CM12 for this Sony tablet. I wouldn't personally consider the Sony until a reasonably complete/stable nightly CM build was available for it. A shame reviewers of Android devices *never* mention CM availability status - to me, it's a major selling point that improves the user experience no end.
