Doesn't seem to be any Nexus 9 Black Friday deals. Samsung has the larger Tab S 10.5 for $399. I have been waiting for 2 years for a Nexus 10 successor and not considered anything else. Now that the 10.5" is same price as N9, I'm debating. I've also heard complaints about quality build on the N9, but not enough official reviews to confirm. Thoughts?
